       他身上有一種文人的儒雅風度,他的名字卻和一系列加速器的頂尖技術連在一起:世界上第一臺醫用電子加速器、中國第一臺高能電子直線加速器……他就是我國粒子加速器事業的開拓者和奠基人之一、國際著名加速器物理學家謝家麟先生。
       近一個世紀的科技人生,謝家麟以兩項世界原創、3項填補國內空白的科研成果,為我國高能粒子加速器從無到有并躋身世界科技前沿,做出了杰出貢獻。2012年2月14日,92歲高齡的他登上了國家最高科技獎的領獎臺。
      
      “我這個人膽子大,敢闖敢干”
      
       對于獲得國家最高科技獎,先生謙遜地說:“我只是很一般的平常人,不聰明也不能干,我能獲獎說明一個人不管資質怎么樣,只要不斷努力就能取得成就。”
       “資質平常”的謝先生卻自稱有一個特點:膽子大,敢闖敢干。他說,科研工作就是解決困難和問題,沒有路可走也要想出路走。
       1952年,回國受阻而無奈留在美國斯坦福大學工作的他接受了一項任務,研制一臺高能電子束醫用電子直線加速器,用它產生的高能量電子束流,打入人體內部殺死腫瘤細胞,治療癌癥。“別人都問我,用加速器治療癌癥,風險這么大,你能睡得著覺?”他微笑著回憶。
       謝家麟拿著100萬美元的經費,和一個招聘來的退伍兵,領著一家化妝品公司的兩個工程師和幾個技術員,與當時由美國芝加哥大學的四名教授和一家大型加速器制造企業組成的團隊展開了競爭。經過兩年廢寢忘食的工作,由謝家麟領導的團隊,硬是搶在了別人前面,建成了當時世界上能量最高、技術要求精尖的第一臺醫用電子加速器并用于臨床,在美國高能物理界引起轟動。“這事奠定了我一生事業的基礎。”他說。
       正當他一舉成名之際,美國移民局給他來信,要他在做美國永久居民和限期離境之間選擇,他毫不猶豫決定回國。有人問他后不后悔當初選擇回國,謝家麟說:“我不但不后悔,而且感到非常慶幸。”
      
      幾代中國物理學家的夢想
      
       在中國建造高能加速器,開展高能物理實驗研究,這曾是幾代中國物理學家的夢想。1972年,由著名物理學家張文裕牽頭,包括謝家麟在內的18位科學家參與撰寫了一份報告,提出建造高能加速器的建議,得到了周恩來總理的批準。
