News From S160 shift crew

20/11/98 08.16.11 Calibration of X vs momentum p and BE(=139.57-Ex(205Pbg.s.)) as determined from the pi0 peak scan varying the SIS energy; p = 0.25562 X + 1689.907 [MeV/c], BE = 6.044 + 0.13197 X.
18/11/98 11.17.44 New display of the 1s-2p region with 2 Gaussian fitting.
17/11/98 12.55.10 'changebin.kumac' was renewed.Now you can use any ratios to rebin.The usage is 'changebin ID RATIO'.For instance in the case you want to rebin histogram ID=807 into 1/10,type changebin 807 10.When [Ratio] is skipped,it will be rebinned into 1/10.
16/11/98 21.31.29 Production run restarted.
16/11/98 21.09.54 Statistical error = +-70 keV for the 1s peak, +-15 keV for 2p
16/11/98 21.01.10 Nov16: acceptance measurement with 12C on 9Be, successful
16/11/98 21.00.14 Nov16; new calibration run with changing d energy
12/11/98 17.29.57 "Run# vs CH2 peak" graph became not to appear data point clearly because x-range is more wider than before. Please comment on new graph.This is temporary but better than before.
11/11/98 20.48.00 News system is revised
Now you can use HTML commands in the content.
11/11/98 20.28.49 again: back to production
11/11/98 20.27.03 dipoles D3 and D4 changed by 1.005/0.9975
acceptance more symmetric
6g/cm2 Be target makes acceptance look even more symmetric
why ???
back to production
11/11/98 20.23.42 acceptance was studied and found asymmetric
09/11/98 22.19.30 Acceptance Measurement using Be9 4g 580 MeV D Beam. Strange Shape of Acceptance! Central Momentum Mismatch?
09/11/98 10.55.16 Beam has been stopped since 3am,Nov9th because of ion source problem.

08/11/98 08.34.57 Chamber threshold found to be 050 (but why?), changed to 03d and new run started.
08/11/98 07.50.14 Beam on again.
08/11/98 07.39.33 Beam off due to ion source trouble. Recovery time unknown.
