在HI-13串列升级工程中,BRISOL需要一台初级束流监测装置放置在靶前,用来在运行时在线监测束流位置的变动情况,作为调整束流及连锁保护的依据。束流监测装置是利用质子束流轰击金属铝箔,通过测量所产生二次电子的强度及位置来判断质子束流在靶前的位置的装置。该装置由处在高电位的一组厚为0.025mm的铝箔组成,两对铝箔可以定义一个带有左右和上下方向,并可以读出二次电子流强度的10mm×10mm的通束孔。通过对
In the HI-13 tandem upgrade project, BRISOL needed a primary beam monitoring device placed in front of the target to monitor changes in beam position online during operation as a basis for beam and chain protection. Beam monitoring device is the use of proton beam bombardment of aluminum foil, by measuring the secondary electron generated by the intensity and position to determine the proton beam in front of the target position. The device consists of a set of 0.025mm thick aluminum foil at high potential. Two pairs of aluminum foils define a 10mm x 10mm through-hole with left and right and up and down directions and a secondary electron flow reading. Pass right
