| | IVC closed and Turbo pumping for a few days. No tower - this is just a leak test. |
| 1110 | Electrical check of shunt resistances on ZC-74, after wirebonding work yesterday. All read 11-13 Ohm, in contrast to yesterday, all reading ~ 20 Ohm. So looks like we successfully reduced the shunts. pC shunt reading was unstable, could be made stable by squeezing plate. So this is another case where we may be losing connection in the middle layer, a chronic problem with this SQUET. |
| 1515 | Modify ZC-31 SQUET to set all Shunt resistances to 6.7 mOhm. Did this in Ke Wang lab, with help of Wei Ren. Changed the power settings a few times - what finally worked was 275/250 for Cu/Gold pads. |
| 1600 | Modify ZC-26 SQUET to set all Shunt resistances to 6.7 mOhm. Did this in Ke Wang lab, with help of Wei Ren. Changed the power settings a few times - what finally worked was 275/250 for Cu/Gold pads. |
