In order to improve the beam feeding capacity of HIRFL,the accelerator team of modern institute of physics developed a continuous wave linear injector for Separated Cyclotron Linac(SSC)(Fig.1).
The distance between two identical Time-Of-Flight(TOF)detectors,which are installed inside 10−11 mbar vacumm beam pipe in the straight section of the storage ring CSRe,is measured by a laser range-finder Leica Nova MS...The distance between two identical Time-Of-Flight(TOF)detectors,which are installed inside 10−11 mbar vacumm beam pipe in the straight section of the storage ring CSRe,is measured by a laser range-finder Leica Nova MS60 MultiStation[1].The objects of the measurement are the two carbon-foils of the detectors with their centres aligned to the ion beam trajectory.The diameter and thickness of the foils are 40 mm and90 nm respectively.Schematic view and picture of the TOF-detector[2]are shown in the left and middle panels of Fig.1.The TOFdetectors are moveable in x direction so that the carbon foil can be placed in and out of the beam line.展开更多
