!EMORANDUM To:
R. Ryan FROM:
F. Rodriguez-Ver DATE:
April 12, 1989
.Per your request this morning regarding information about fission chambers to be used along with the Fuel Assembly For Fissile Assay (FAFFA), for the "Fissile Assay of Spert Fuel Using Slowing-Down-Time Device" project, the following should be stated.
A.
We have 11 fission chambers that we intend to use at several configurations around the FAFFA, when placed inside of the lead spectrometer. However we do not plan to use all 17 chambers at the same time. A typical arrangement would be as that shown in Fig. 2.2 "Lead Spectrometer Arrangemint" of E. Vanterpool's PhD thesis (enclosed).
B.
The type, serial number, fissile/fertile material, and amount for each chamber is given as follows.
1.
WX32504-743501 0.36 gr Th-232 2.
WX32504-771302 0.36 gr Th-232 3.
