Opened the ATTS, placed what I will call “Cast Alumina Sample #1” into the ATTS and activated the roughing then turbo pumps. Currently sample
is in slow heating progress to 1000 degrees Celsius, process is expected to take some time, so I'll revisit after lunch.

|
A major leak was found on the connection to the regulation valve on the He bottle. Ferrule replaced. System leak checked.
After He bottle: base 5E-6, no response to He spray
AfterSV1: base 5E-7, no response |

|
New supply of He and Ne was installed yesterday and gas lines leak checked. The He bottle is currently closed.
UPDATE Monday, June 17, 2013, 15:17
Specifications for the currently installed Ne leak (SN: 11-231) can be found on DocuShare |

Wednesday, May 16, 2012, 19:55, Friedhelm Ames, , , , , , , Problems/Solutions, Hall probe reading wrong
|
During the mass scan today it was discovered, that the mass calibration was off. Further investigation showed, that the Hall probe readings are a factor
of 1.31 lower than during previous measurements. A fault report has been issued to controls. |

|
Jens Lassen provided a new controller for the Hall prove. With the help from Graham from controls it was reconfigured and is operational again. The magnet
must likely be calibrated again. |

New calibration of the m/q based on the hall probe after exchanging the controller(MASSOVERQ2). Based on NiO#2-HP-FEBIAD with Ne supplied and ANODE
biased to 200V, 30kV Bias.

First attachment: BIAS/EE/EZL = 63.25/-1.5/31 So far no issues.
Second attachment: BIAS/EE/EZL = 64.25/-1.5/32 Slight spark - bias current jumped from 40uA to 88uA and vacuum jumped from 2e-7 to 2e-6... Steerers
went off. |
