1) Action items
Action 36: Report by Redkina is ready, should be made available on the PHAROS wiki.
Action 90: To be finished Jan 2007
Action 107/130/131: to be discussed at the Torun meeting
Acton 152: Done, to be send around
Action 153: Done, 31st – 2 Feb 2007
Action 155: Fits in 20x20x20 cm
Action 159: Weights for ASTRON antenna design details
Action 164: Done, to be send to the partners (JGBdV)
2) Annual Report
Needed for the annual report:
-manmonths personnel
-manmonths staf (AC partners)
-a summary write-up for each workpackage
-spending in euros on manpower, travel, mmics and hardware (for the 18month forcast)
Since the annual report will also functions as input for the midterm review (by EU reviewers), a more comprehensive reporting is required. Therefore more input from the workpackages is required to stengthen the write-up: deadline 19th Jan to be send to JGBdV!
(no strict size constraint but e.g. ~ 2 pages, 1 page text 1 page figures, a little input from 2004/2005 is allowed to complete the report).
For the 18 month forcast also the complete financial data is required. These are the same numbers as on the totals on the C-form.
3) Progress Work packages
-Beamformer Design
Work will restart in Feb.
-Filter design / production
Meeting scheduled in two weeks to discuss progress.
-MMIC rap-up
MECSA finished the modifications and re-test of the Mercury chips. All components of two wafers have been shipped to Manchester. A detailed report on the results is available.
The 70nm run is now scheduled to be finished by March 2007.
-Cryostat design
One Window has been ordered. Production time is about three months. Scheduled to be finished by 1st of March.
The Window will be shipped to ASTRON for RF testing (March time frame).
Approval needed to start the production of the cryostat (action ASTRON).
In order to optimize the design of the flench more details of the local mounting are required. Action for UMAN and WSRT.
-Software –System control
A meeting Torun has been scheduled for end of Jan. Jan Simons and Dave Glynn will attend the meeting.
4) Focal Plane Array Workshop
The 3rd Focal Plane Array workshop will take place in Sydney, 12th – 14th March 2007. And a PHAROS meeting is now scheduled for Friday 16th March in Sydney. All partners are invited to join the workshop as well as the meeting!!
