a) Fabrice: Magnet position on the target platform checked within +-1 mm.
The thermal screen suspensions inside the vacuum vessel modified since
2011 and the aluminium screens between the dilution cryostat and magnet
need a small modification. The PTFE support under the glassfiber ring
fixed on the cavity needs to be modified too. Now only short section of 
the ring on the bottom of the magnet bore is going to be used. This 
circular support can be put in place with long aluminium rods from the
downstream end of the magnet after inserting the dilution cryostat into
the magnet.

b) Meeting at CERN central workshop on Monday morning to discuss new target
holder parts. Cost estimate being prepared.

c) Kaori: test CPI power supply on Monday. Instead of EIO tube microwave
generator a dummy load resistor was installed into the high voltage
connection box to simulate the heater filament. Normal operation without
error messages from the CPI power supply.

Reconnect EIO tube and test the tube oscillation on Wednesday. Frequency
control is working too. Then a long time test in standby mode of the
power supply.
 
d) Norihiro: test new servomotors for the control of needle valves.

e) Magnet operational parameters can be communicated to the DCS system using
DIP server. 

f) Prepare dilution cryostat for insertion into the magnet. The cavity 
cooling loop closed with copper seals and downstream thermometer glued on 
the cavity surface. Install outer support ring made of glassfiber. Remove
old vacuum gauges that are going to be replaced with new ones. 

g) Target control room temperature at +28 - +30 C due to missing cooling
water for the air conditioning unit.
