Focal plane detector for the S800 high-resolution spectrometer

Population of positive-parity states inSc53through one-proton knockout

“…The setting without momentum restriction was optimized for two-proton knockout to 52 Ca [14], and the 53 Sc residues only entered the focal plane at the edge of the acceptance. The S800 focal-plane detection system provided energy-loss measurements, timing information, and positions and angles of the projectile-like reaction residues [17]. An example of the particle identification is given in Fig.…”

Evolution of the momentum distribution with mass loss in projectile fragmentation reactions

“…Fragment identification was performed using a combination of detectors in the focal plane. An ionization chamber measured each particle's energy loss [17] and the time-of-flight of each particle was measured as the time difference between two plastic scintillators located at the object position of the S800 beam line, and one downstream of the ionization chamber in the focal plane of the spectrograph. The residual energy signals from a newly installed CsI(Na) hodoscope [18] array were used to identify charge states of the fragments as part of the particle identification scheme and remove unwanted events from the analysis.…”

“…The energy loss (∆E) and TOF of the residues were measured with an ionization chamber and a plastic scintillator, respectively, which were located in the focal plane of the spectrograph [37]. The reference for the TOF measurement was provided by the signal from the in-beam diamond detector.…”
