a) The Horizon2020 - HPH Joint Research Project Brainstorm Meeting on
"Dedicated Magnet Systems for Polarized Targets" took place at Bonn
Physics Institute on Tuesday January 21 2014.

b) Norihiro: new servomotors expected after March 10. The motor control
from Siemens PLC with Profibus. 24 VDC/10 A power supply needed for the motor. 

c) Yuri: update trim coil field calculation program to Mathematica 9.
Spectrometer magnet SM1 fringe field is small and can be neglected.  
The protection diode switching simulation on the trim coils to be done.

d) Fabrice: magnet cooled with LHe now and reached already 37 K. Filling with
LHe expected next week. After this tests of superconducting properties of
the magnet coils will continue. The power supply cables are being prepared.
Isolation vacuum at ~10^-8 mbar and helium consumption during cooling down
about 1 g/s or 30 l/h of liquid. Heating cable installed on the necks and
previous return gas heater reused.

e) Kaori: waiting for Lauda microwave water cooler, miniature NMR cable,
SMA connectors and National Instruments ADC board. New small NMR rack to be
found.
