The superconducting cyclotron, a key component for mainstream proton therapy systems, is likely to become fully commissioned next year for clinical trials, making it the first of its kind in China, according to Zhang Tianjue, director of the Cyclotron Research and Design Center of CIAE.
Proton therapy, or proton radiotherapy, is a type of therapy that uses a particle accelerator to irradiate diseased tissue with a beam of protons, most often as treatment for cancer.
Compared with conventional radiotherapy, proton beams will only release a large percentage of radiation dose when they reach a tumor, which means it will kill the cancer cells while leaving healthy cells intact, according to Zhang.
"About 73 percent of installed proton therapy systems in the world use cyclotrons to produce proton beams, according to Lyu Yinlong, deputy director of the center.
With proton therapy systems being used for domestically made accelerators, treatment costs for Chinese cancer patients will be largely reduced, said Zhang and Lyu.
If patients opt for proton therapy with imported systems or abroad, the costs could more than double, they said.
In the same year, it acquired a 49.9 percent stake in Malaysian automaker Proton and bought flying car company Terrafugia Inc. Geely also owns Volvo Cars, which has been helping Geely with technology to seize a larger share of the Chinese car market.
However, the COVID-19 pandemic affected the process, which included the construction of a proton therapy center and the installation of the proton radiation therapy system, the most advanced equipment of its kind in South China, Qian said.
It took 81 containers to transport the proton therapy equipment from abroad.
More than 100 engineers spent over two years to complete the installation and commissioning of the proton system, he said.

Proton is expected to launch at least one NEV model a year with the help of Geely Holding Group, which owns a 49.9 percent stake in the Malaysian carmaker.
Geely Chairman Li Shufu said the company's global network of innovation, advanced vehicle platforms, product portfolio as well as its human resources will sharpen Proton's competitive edge.
Li made the remark when Proton launched on Sunday its first NEV model, the X90, which was introduced from Geely.
He said Geely will train 5,000 NEV professionals with Proton to grow the Malaysian marque into a leading NEV player in the ASEAN.
Geely inked a deal with Proton's parent DRB-HICOM Berhad in April to facilitate NEV development in Malaysia.
Geely purchased its stake in Proton in 2017 and has since been boosting the brand's development with both technology and models.
Statistics show that Proton's sales soared from 64,744 units in 2018 to 141,432 in 2022.
Besides its stake in Aston Martin, Zhejiang Geely Holding Group owns Swedish premium brand Volvo and holds stakes in international marques including Daimler, Proton and Lotus.
Malaysian carmaker Proton, in which Geely bought a 49.9 percent stake in 2017, exported 2,722 vehicles in the first half, up 81 percent year-on-year.
Geely Auto Group CEO Gan Jiayue said on Thursday that Lynk & Co will continue to promote Europe and Asia-Pacific strategies; Geely-branded vehicle will focus on the Middle East, Asia-Pacific, Latin America and others; Proton will focus on the Southeast Asian market and accelerate expansion in Thailand, Vietnam and other emerging markets.
"As the first step, we will have 300 outlets in 14 European markets, including the United Kingdom and Switzerland," said Tong, who added Smart is working with Malaysian carmaker Proton to introduce the brand to Southeast Asia.
It has also helped rejuvenate Malaysian carmaker Proton, in which it bought a 49.9 percent stake in 2017.
He said smart is working with Malaysian carmaker Proton to introduce the brand to Southeast Asia.

"The company said CMA, along with a smaller car platform designed for Proton, allow them to harness Volvo's technologies and Geely's capabilities in cost control, supply chain management and local production.
Li confirmed the Proton plan during an interview with Reuters.
His holding group also owns London Electric Vehicle Co, a 49.9 percent stake in Malaysia's Proton, a majority stake in British sports car brand Lotus and a 9.7 percent stake in Mercedes-Benz parent Daimler.
Last October, Volvo said it would merge its engine development and manufacturing assets with those of Geely, creating a division to supply Lotus, London Electric Vehicle Co, Lynk & Co and Proton, and also potential competitors with next-generation combustion and hybrid engines.
Malaysian carmaker Proton started production of its popular X70 SUV, which is based on Chinese stakeholder Zhejiang Geely Holding Group's Boyue model, on Friday at its plant in Tanjung Malim, paving the way for its ambition of becoming the No 1 brand in the country.
Founded in 1983, Proton has reported losses for years and had resorted to state aid for survival, hit by intensifying competition from Japanese rivals such as Toyota Motor Corp's Daihatsu and Honda Motor Co. Geely, owner of Volvo Cars and also a stakeholder of German auto group Daimler, has been injecting cash and new technology to help Proton's turnaround since it acquired 49.9 percent of the company in 2017.
With Geely's help, Proton launched five new models over the past year including the popular X70 and saved at least $50 million in costs, said its chief executive Li Chunrong in an interview with Reuters.
Geely and Proton have invested over $288 million to expand and upgrade Proton's manufacturing facilities at the Tanjung Malim plant, which will also be capable of producing other Geely models.
Proton Chairman Syed Faisal Albar said, "By updating and expanding our industrial footprint in Tanjung Malim, we are now better placed than ever to grow Proton as a global brand.
""This updated plant will not only produce future products jointly-developed with Geely, but will also be a center for right-hand drive production as we begin to export Proton vehicles to global markets.
"Proton wants to claim the top position in Malaysia and become a top three player in Southeast Asia where it currently ranks the ninth biggest, as it looks to export to the key markets of Thailand and Indonesia.
Li said Proton could return to profit this year after years of losses, driven by new product launches and aggressive cost-cutting under joint management with Geely.
He told Reuters that Proton is likely to set a 2020 target of a 30 percent rise in vehicle sales from 2019.
Geely President An Conghui said, "We will continue in supporting Proton with leading technology as it grows in the Malaysian market, as well as in the wider ASEAN region and beyond. "
Besides Volvo Cars, Geely has stakes in Volvo Trucks, Mercedes-Benz owner Daimler, sports carmaker Lotus and Malaysia's budget brand Proton.
It is also featured in Proton models, a Malaysian brand of which Geely acquired a stake in 2017.
Zhejiang Geely Holding Group, owner of Volvo Cars, purchased a 49.9 percent stake in Malaysian carmaker Proton in June 2017.
In May, Proton sold 10,711 vehicles, a 46-month high.
Daniel Donghui Li, chief financial officer of Geely, said one reason why Proton singled out Geely from others was that the Chinese carmaker had a unique vision for Proton's future development.
The results so far are showing that we are on the right path," said Li, who is also a Proton board member, in late April.
Proton's burnished performance was mainly thanks to its model X70 launched in December.
In fact, it has introduced for Proton a comprehensive strategy covering aspects from personnel, product quality and cost control to research and development and plant renovation.
Proton engineers are also joining Geely's research teams in Ningbo, Zhejiang province, and the two sides are working to find solutions that will enable Proton to benefit most from Geely's proven system.
Ahmad Muzaimi Zainol, a Proton project manager, said after two years of cooperation, they have seen encouraging progress.
Geely is helping Proton to revamp its plants as well.
Proton Chairman Syed Faisal Albar said that the two companies' partnership has proved to be a shining example of cooperation between both countries.
China's Industry and Information Technology Minister Miao Wei said during the plant's opening ceremony that Geely and Proton should seize the opportunities provided by the Belt and Road Initiative, and urged them to deepen cooperation to offer globally competitive products.
Li said the model has refreshed the public image of Proton and boosted its market share to 12.7 percent in the first quarter, up 3.2 percentage points year-on-year.
Another two updated Proton models were launched earlier this month, helping to further boost the confidence of the carmaker and its 175 dealerships.
Daniel Donghui Li, chief financial officer of Geely and a board member at Proton, said one reason that Proton chose Geely from three rounds of global bidding was that the Chinese carmaker had a unique vision for Proton's future development.
By 2027 Proton will have annual sales of 400,000 to 500,000 vehicles, which will account for 8 to 10 percent of Geely's total sales, he added.
A number of models are planned for Proton, according to the company, ranging from compact SUVs to sedans, MPVs and crossovers, with Proton and Geely engineers deeply involved in development.
Besides introducing new models, Geely has been helping Proton to strengthen its management and improve its quality standards.
As Proton makes rapid progress in Malaysia, it is soon to build its first overseas assembly plant in Pakistan with local partner Al-Haj.
Proton said the plant's annual production capacity is expected to reach 25,000 vehicles in four years.
Also on Friday, Proton inked a deal with China Construction Bank for a 3.1 billion loan that is expected to further its research and development and improve its manufacturing facilities.
"Expansion to more foreign markets is critical for sales growth while obtaining financing allows the company to invest in the many projects required to turn Proton into a truly global automotive brand," said Sri Syed Faisal, managing director of DRB-Hicom and chairman of Proton.
So far we have invigorated Volvo, and see synergy emerging among Geely, Volvo, London Electric Vehicle Co and Proton in terms of culture, human resources and technology.
In 2013, Geely bought London Taxi Co, the UK-based manufacturer of London's municipal cabs and renamed it London Electric Vehicle Co four years later, and bought a key stake in Malaysia's Proton in 2017.
"One of the latest examples came from Proton.
The model "introduces Proton to a new market segment and is the key catalyst for the total rejuvenation of the brand," said Proton in a statement.
In the 1980s, he oversaw the establishment of the nation's leading car manufacturer Proton as a joint venture between the Malaysian government and Mitsubishi.
It will be the Chinese carmaker's first move to shake up Lotus since its purchase of a 51-percent stake in 2017 from Malaysian carmaker Proton as part of a package deal with its parent company DRB-Hicom.
After the purchase of Volvo Cars from Ford Motor Co in 2010, the carmaker snapped up stakes in the iconic British sports-car maker Lotus Cars and Malaysia's Proton Holdings Bhd last year.
Zhejiang Geely Holding Group and Malaysian car manufacturer Proton on Saturday agreed to establish a joint venture to deepen their cooperation in new energy vehicles and promote Proton cars in global market.
Geely and Proton will each hold a 50 percent stake in the joint venture.
While Geely is willing to help Proton with innovation and market expansion, it is also expecting to tap the Southeast Asian market through this cooperation, according to Yang Xueliang, spokesperson for Geely.
据吉利汽车发言人杨学良表示，虽然吉利愿意帮助宝腾实现创新和市场拓展，但同时也期望通过这种合作进入东南亚市场。
Last year, Geely acquired 49.9 percent of Proton from Malaysia's leading conglomerate DRB-HICOM that owns 100 percent of Proton.
去年，吉利从马来西亚领先企业集团DRB-HICOM手中收购了宝腾汽车49.9%的股份，而DRB-HICOM拥有宝腾汽车100%的股权。
Besides Daimler and Volvo, Geely now owns British taxi manufacturer The London Taxi Company, UK sports carmaker Lotus and Malaysian automaker Proton Holdings as part of its drive for a slice of the lucrative Southeast Asian market.
Hydrogen fuel cells, which creates electricity by splitting hydrogen electrons from the protons, is believed by experts better for trucking than the battery cells used in most electric cars like Tesla because the system is much lighter.
