• Cosmic paddles and trigger preparation.
• Gas preparation.

ROC Preparations

• ROB aging and tests. Thanks Ivan, Jorge, Stefan.
• Capacitors patchworks. Thanks Behrooz.
• Mounting HV filter boxes were well done. Thanks
  Raphaelle, Silvia, Anton, Christian, Behrooz.
  Technology transfer was done. It is expected that
  ROC production sites can do it.
• Some problem in/around HV filter box found by
  Rainer (necessary for applying HV before going to
  SM after HV is put).
• Mounting ROBs were well done. Thanks Raphaelle,
  Silvia, Anton, Christian, Behrooz). Many people
  know how to do.
• Cable channel preparation. Thanks Clemens.
• Long HV cables attaching.
• gateDB is fine! Thanks Tom.
• Allready prepared ROCs
• 4 x L0C1
• 1 x L0C0
• 4 x L1C1

5
Power-Bus-Bar and ROC Installation

• Almost no geometrical problem except for around
  drift HV wire.
• Excellent preparation of the cage by Bernd and
  his team.
• Power bus bars were attached onto side-panel by
  double sided tape spacer (with same thickness
  as cooling pipe). Thanks Christian, Tom.
• Lying chambers takes only few hours. Gas
  interconnection is so easy!

6
ROB L.V. Connections, etc.

• Cable length was optimized for L0 L1, and
  produced by Tom.
• All cables are screwed onto power bus bar using
  cable shoes.
• 304 screws connections were finished. Thanks to
  people (Raphaelle, Silvia, Anton, Christian, Tom,
  Chilo and more) although difficult positions!
• Later, power bus bar side panel LV cables are
  pre-assembled.
• H.V. Cabling space is fine.

7
A and C Sides Preparations

• 4 x 1000 uF capacitors are put on each power bus
  bar end. Will be more.
• TTC Fibers and Shuetten Box were installed.
  Thanks David.
• Davids HV patch panels (driftleft and
  anoderight) were placed in preliminary positions
  and 5 chambers are connected.
• Gas connections were done. Thanks Chilo and
  Clemens.
• DCS Power cables and Ethernet were placed. Thanks
  Christian.

Powering up and Configuring 1st-SM Layer-0

• DCS Power OK.
• LV on power bus bar OK.
• H.V. OK. (Clemens saw problem in one of the
  chambers).
• Ethernet there was problem with certain switch
  but not with Cisco switch or 24 port NETGEAR
  switch. Shielding and DCS groundings do not help
  for bad switch (unshielded is bit better).
• ROCs were connected to bus bars one by one.
• TRAPs successfully configured!!
• Stand-by (wait_pre) power consumption
• A3.3 50 A
• D3.3 20 A
• A1.8 70 A
• D1.8 60 A
• Significant voltage drop resulted over-voltage
• trip at P.S. due to thin LV wire (16 mm2).
• Solved by 70 mm2 wires.
• Thanks for Marc, Tom and .

9
Optical Fibers Installations

• It is just easy to run on ROCs (over cooling
  pipes).
• Installation might be difficult and risky when
  big cooling pipes are there.
• Replacing of ROCs anyway almost impossible
  (possible one by one from side, due to gas
  interconnection etc).
• Mixing with and damaged by heavy cables (power,
  HV) can be avoided.

10
Trigger Preparations

• Scintillation paddles for cosmic trigger were
  prepared by Marc and Min-Jung. Super-module can
  be scanned by cosmic trigger.
• TTC trigger propagation test by Marc and
  Min-Jung
• TTCex ? Shuetten Box ? TTCrx ? TRAPs
• were tested and all event counters were ok.
• Pretrigger system must be tested
• for triggering TRAPs with pretrigger,
• L0, and L1. Overall jitter measurement
• is necessary.

11
Missing Items for 1st-SM Completion till P.C. in
May

• 20 more prepared ROCs for L2 L5.
• LV distribution scheme on the front of SMEC must
  be fixed before Layer-1
• Wiener LV PS (coming soon).
• Power bus bars (ordered by Christian and some
  more already arrived).
• Power bus bar safety covers capacitors LEDs
  modules.
• Cooling pipes on ROBs (almost done by Ana).
• Cooling pipes below power bus bars, and on the
  SMEC.
• DCS power distribution box (design have done by
  Dirk and Mr. Rausch).
• Final Ethernet cables (exotic cable is expensive.
  normal CAT5 fits).
• JTAG cables (metric PVC cable was rejected. 2.54
  mm flat solution is taken).
• ORI fiber patch panel ?
• ORIs (being produced).
• GTU
• Pre-Trigger System (at least the Control Box).
• Some more in gas system?
• HV Distribution Box (Greek Box).
• LV diagnose sensor (voltage divider).
• Temperature sensor (well known).

Conclusions

• ROC preparations are on going without big problem
  and technology was transferred.
• 1st super-module Layer-0 test started.
• No problem to power up 5 chambers and configure.
• Noise level 1.17 LSB (1230 e) outside SM ? 1.09
  LSB (1150 e) inside..
• But bad channels were introduced by moving into
  super-Module.
• Preparation for full chain test including
  control system and DAQ is on going right now.
• Still there is significant number of missing
  components.
