TileCal Status: Cabling

Cabling for most(?) sectors now in place...

apart from trigger cables which are only installed in sectors 13, 9 and recently 5

New Nexans cable is now available

remaining trigger cables will all be installed in the next few weeks

New order to Nexans in about 2 weeks

for Extended Barrel trigger cables

do we want to add to that order or do we have enough for all our short cables?

TileCal stocks are available, only one installed

suggested to Irakli that he tries it and then installs the others as required

TileCal Status: LV PS

Problem with LV power supplies

Some frontend electronics damaged

Problem understood, but LV PS off until fix is tested

Medium term (2-3 weeks)

fix 20 LV PS (enough for 1 sector plus some spares)

Longer term (september?)

fix all LV PS together with mod to reduce noise

Commissioning continuing with one temporary PS

But we have not been looking at signals during this time – should we?

Expect to resume L1Calo TileCal testing once they can power a whole sector (early April)

TileCal Plans

Expected cosmic ray run with LAr in May/June

Trigger on 12 modules * 2 sides at top and bottom

Using L1Calo outputs from TCPPs

However they will not have enough LV PS for this...

...and LAr also have PS and cooling problems

Keen interest in integration with L1Calo

Test full data chain, ie RODs, ROS

What do we still need for this?

ROD: in PPM crate as no TCM for ROD crate yet?

RGTM(s) for two PPMs at CERN

Connection to ROS

Online monitoring L1Calo/Tile and/or

Bytestream decoding in ATHENA and analysis code?

LAr Activities

All receivers installed (including TileCal)

Apart from rear transition modules which need a short repaired (by Chaouki & Vikas at CERN)

LAr Barrel being tested via receiver system

Readout to VME FADC via monitor board

So far still using temporary cables to USA15

They can see pulse shape without need for PPM

But recently they asked about tests with PPM

We have still never looked at LAr signals in USA15

We (Frederik) did lay a fibre for their TTC signals...

But standalone LAr test crate now moved near us!

We need to schedule LAr and resumed Tile tests

USA15 (1)

So far very little final L1Calo installation

Both ROD crates, 4 (of 6) RPPP crates, all 4 TCPP crates

Final TCPPs are at CERN, but over half still need screw locks fitted – hopefully they can be installed next week

VP315s delivered – return two loan pool CPUs next week

Temporary stuff

6U TTC crate – pending final TTC crate

Two (of 8) PPM crates temporarily relocated (for cabling)

Few stocks being moved around, though they have all now been delivered (still with rough edges)

NB some flying leads used for TileCal cable tests removed for cabling work – need to be reinstalled

USA15 (2)

To be done (apart from obvious stuff)

Power: for switches, also change of PPM crate power

Cable trays and supports

Front of racks for fibres, network etc

Underfloor for LVDS

Rack doors: do we want anything for PPM/receiver racks?

Reminder: cryostat filling & magnet tests start soon

Safety course 4A now required!

3150

Network finally active!

New network cabling finished a few weeks ago

Switches and new wireless active since Friday

Gigabit in the building, but only 100Mb/s to CERN (until planned backbone upgrade reaches us)

Only 4 ports per room, so we may want to get (free!) 5 port switches from IT department

Miscellaneous

Building has been cleaned (once) recently

Other parts of TDAQ may like some space here too...!
