Jan. 98 proton irradiation at KEK
(and subsequent beamtest)
Updated: Dec. 16, 1997

Fluence:           3 x 10^14 protons/cm^2
Irradiation time:  Jan. 13 - 15?, 98
Installation time: Jan. 9, 98
Extraction time:   Feb. 3?(from beamline), Feb. 10? (from radiation section)

Samples: n+(n) and p+(n) detectors

Size:  64 mm x 63.6 mm x 0.3 mm thick, otherwise mentioned

In cold environment:
 1st row:
  (1) Hamamatsu n+(n) baseline                                        2
  (2) Hamamatsu n+(n) new p-stop                                      2~4
  (3) SINTEF polyimide passivated p+(n) (With Ceramic+PA)             2
  (4) CIS wedge p+(n)  (With Ceramic+PA)                              2~4

In warm environment:
 2nd row:
  (5) SiC pad detector (~1 cm x ~ 1 cm x 500 um?)                     1
  (6) Mechanical grade detectors                                      4
  (7) Mechanical grade detectors                                      4

Notes:
- Samples, (1) to (4), are on the ceramic board with pitch-adaptor(PA),
  and wire-bonded (detector-PA, and PA-ground)


Four samples on ceramic/PA are going into the beamtest being planned 
immediately after the extraction. 

Beamtest: Feb. 19? - 28?, 98

Irradiated detectors:
  (1) Baseline n+(n)
  (2) New p-stop n+(n)
  (3) SINTEF p+(n)
  (4) CIS wedge p+(n)

Module:
  (5) OZ1 forward module
