《研究与发展杂志》近期发表了一篇技术评论文章,对桌面粒子加速器的最新进展进行了评述。 提起粒子加速器,人们一般都会想到长达数公里的大型加速器,而事实上可放在桌面上的粒子加速器已经问世,并将用于超速科学研究。 桌面粒子加速器虽然要比大型加速器功率小得多,但其所射出的短脉冲电子束都可以用来对在毫微微秒的时间内发生的现象拍照,因而生物学家、化学家和物理学家可以用它来研究实际的瞬态反应。 除了用于超速科学研究外,桌面粒子加速器预计在3年内可用在医学领域,并且可望取代昂贵的大型射频线性加速器(RF-linacs)。射频线性加速器目前广泛用于医院和实验室中,用来产生供治疗和成像用的同位素和X-射线。 The Journal of Research and Development recently published a technical commentary on the latest advances in desktop particle accelerators. With particle accelerators, people tend to think of large accelerators up to several kilometers long, and the fact that particle accelerators can be placed on the table has come out and will be used for speeding scientific research. Desktop particle accelerators, although much smaller than large accelerators, emit short pulses of electrons that can be used to take pictures of what happens in femtoseconds, so biologists, chemists, and physicists It can be used to study the actual transient response. In addition to being used for speeding scientific research, desktop particle accelerators are expected to be available in medicine within three years and are expected to replace expensive large RF linacs. RF linear accelerators are currently used in hospitals and laboratories to generate isotopes and X-rays for therapeutic and imaging purposes.
