Abstract

The performance of a plastic phoswich (400 μm NE102A + NE115) as an element of the focal plane detector for magnetic spectrographs was studied. When combined with the p/q selection by the spectrograph, the phoswich provides a complete isotope separation for light heavy ions in the energy range of some tens of MeV/nucleon.

Identification of heavy ions in magnetic spectrograph measurements using a plastic phoswich
1996, Nuclear Instruments and Methods in Physics Research, Section A: Accelerators, Spectrometers, Detectors and Associated Equipment
Plastic phoswich detectors, consisting of a 400 μm fast scintillator (BC400) and a 22 mm slow scintillator (BC444), were used for heavy ion identification in magnetic spectrograph measurements. While the light output from the phoswich in a fast time gate was sensitive to the Z separation when combined with a Bϱ measurement, the light output in a delayed-long time gate provided mass separation. The method of particle identification with the plastic phoswiches is described in detail.
Calibration of phoswich detectors
1992, Nuclear Inst. and Methods in Physics Research, A
Two important aspects for the calibration of phoswich detector arrays have been investigated. It is shown that common gate ADCs can be used: The loss in particle identification due to fluctuations in the gate timing in multi-hit events can be corrected for by a simple procedure using the measured time difference between gate and phoswich signal. The response of phoswich detectors to particles with given Z, A and E was studied using a magnetic spectrograph. In the absence of mass identification the energy calibration is limited by the width of the experimental mass distribution for a given element.
