Attachment 1 shows a comparison of the zero-degree telescope from the decay measurement with the 26gAl beam produced today (left side) and a GEANT4 simulation
by Shimizu kun
some months ago.

|
Today we took datas of NaI detectors one by one for calibration. The gamma ray source was put on the NaI surfaces so that peaks could clealy appear where
we expected.
We fitted them with gaussian and exponential, and integrate the peaks to calculate yields. The results were pretty good. |

Here I make a running log for CRIB general notes that may be useful for future experiments.

|
Yesterday we improved NaI spectra by checking them one by one with lead blocks stacked as a housing. Though the threshold levels of CFDs were few mV
or less than 20mV and a bias of NaI7 might be high (~1500V), the shapes of spectra looked OK. Now 511keV peaks are around 1500ch in every sprctra.

|
Today we set up and labelled the amplifiers and feedthroughs from E7 to J1. Unrelated to that, when we arrived at 13:45 the F3 pressure was 1 x 10^-3 Pa,
and at 19:45
departure it had dropped to 9 x 10^-4 Pa.
