a) Estimate received from main workshop for the target holder stainless 
steel beam window NA58PT20131106-1, Kevlar tube fixing piece NA58PT20130809,
upstream microwave stopper/cable guide NA58PT20131129 and drilling holes
to the Kevlar tube. The cost 11.68 kCHF includes manufacturing materials.

b) Insert dilution cryostat into magnet on Tuesday. Small initial 
misalignment measured from the cavity downstream end with 2 mm too much
to Saleve side. This was fixed by inserting circular support section under 
the glassfiber ring around the cavity. Thus the top part of the support is 
not used, see the photo from the original installation

c) Norihiro: downstream radiation screen made of aluminium foil after 
the microwave cavity was damaged in the storage and had to be replaced.
The downstream re-entrant vacuum window closed with o-ring. Some damage
on the o-ring surface observed.

d) Closing the magnet and dilution cryostat vacuum space and initial leak 
testing was discussed.

e) Start using powered USB hub for serial devices in the control room. Now
reading six pressure displays at the same time.
