C-GEn "Plan B" Polarimeter

Possible scintillator hardware

The "Plan B" design requires:

  • Total: 136x 10 cm x 10 cm "thick" bars
108   10 cm  x 10 cm x 160 cm   E counters (top + bottom)
 28   10 cm  x 10 cm x 160 cm   analyzer bars
  • Total: 80x 1 cm x 10 cm "thin" bars
 52    1 cm  x 10 cm x 160 cm   dE  (top + bottom)
 28    1 cm  x 10 cm x 160 cm   analyzer vetos
  • All bars are double-ended readout.

Existing Scintillator Bars

BLAST bars (some from PSI LADS detector)
 Ohio walls: 16x      10 cm x 22.5 cm    x 400 cm
 LADS15:     28x      15 cm x 14.5 cm(*) x 160 cm
 LADS20:·    28x      20 cm x  9.8 cm(*) x 160 cm
 (*) bars are trapezoidal shaped; this is mid-point thickness
  • Availability: Yes (needs to be shipped to Kent St/JLab)
  • Location: BATES
  • Contact: Michael Kohl
  • References: NIM A 603 (2009) 247–262 (BLAST detector), NIM A 373 ( 1996) 374-38 (PSI LADS reference)
  • Notes:
    • Bars would need to be cut and polished
    • The LADS bars are trapezoidal; they can be stacked into planes by alternating the 'wedge' direction
    • Needs new PMTs
