  1. Temperature of SVD2 Be chamber Update 2003/11/27 Samo Stanič We monitor the heat taken away by parafin cooling: P[W]=34 * dT [K]

  2. HER dT(1A)=0.4 deg Pmeas(IHER=1A)=14W

  3. LER dT(1.4A)=0.5 deg Pmeas(ILER=1.4A)=19W

  4. HER+LER dT(1.1A+1.4A)=1 deg Pmeas(1A+1.4A)=34W

  5. Estimate of heating power in Be at maximal beam currents T(I) =Tconst +dT(I) T(ILER)= 0.2+0.3 I2 T(IHER)= 0.2+0.4 I2 T(IHER+ILER) between 0.2+0.4 I and 0.2+0.15 I2 dT(ILER= 1A)=0.3 deg dT(ILER=1.4A)=0.5 deg dT(ILER=2.5A)=1.9 deg(65W) dT(IHER=0.6A)=0.2 deg dT(IHER= 1A)=0.4 deg dT(IHER=1.5A)=0.9 deg (30W) dT(1.5A+2.5A)=2.8 deg Pfit(1.5A+2.5A)=95W (was 115W) Pfit(4A) between 55W and 85W
