228Th Source
Measured γ and n emission (see separate note)
1 custom (14.8 kBq @LNGS) and 2 commercial sources(40.9 kBq @LNGS, 24.0 kBq @UZH) available
Calibration System
All 3 absorber rings mounted
One lowering system includingabsorber successfully testedmanually

To Do
Custom 228Th Source
Estimate background from sources in parking position (finalizing)B < 10−4 cts/(keV kg y)
Estimate background due to neutron activated isotopes (in progress)During calibration mostly 41Ar plus 51Cr, 56Mn, 59Ni in the cryostat wall
Source production
Calibration System
Test motor for lowering system (this week)
Pulse Shape Analysis
Updating MaGe on Phase I detector specifications (started)
Data Analysis
See Laura’s talk tomorrow
