1. L1Calo L1 Coordination Meeting March 24th, 2015 Rainer Stamen

2. L1Calo Phase-1 System

3. Status of PDRs Done – FOX – 24.11.2014 – eFEX – 12.2.2014 – jFEX - 31.7.2014 – gFEX – 14.11.2014 – HUB – 1.10.2014 – ROD – 17.6.2014 – FTM – 24.1.2014 (L1Calo internal) To be Done – Backplane usage specification – TREX Proposed date: Week of May 26th-29th Supposed to be end of april, availabilty of people difficult until mid may, week before is TDAQ week, – L1Topo (Changes to Phase-0 L1Topo) Potentially small modifications, need first to learn shortcomings of L1Topo during run-2 All successfull

4. Incoming Reviews TREX – Preparation well advanced – Currently evaluating which requirements to implement and how to implement them – Attractive option identified: usage of FELIX, early retirement of L1Calo RODS – Recosting ongoing (driven by FPGA (driven by requirements)) – Prototype: probably big solution; implement everything (expensive) – Production: implement what is needed (not so expensive) Backplane usage specification – Preparation well advanced

5. Actions from Reviews About 150 actions – 12 ATLAS – 57 L1Calo – 79 Module 1/3 solved by end of last year (Need to update these numbers) Many actions progress as we get deeper into the design We should go through the open items and probably call for a special meeting (Weekly meeting too much packed to discuss details)

6. Meetings with calorimeters Meetings with calorimeters went quiet We met with the LAr Phase-1 coordinators – Agreed that we need to revive meetings – Areed to outline agenda for a few weeks in advance – Agreed to organise a meeting (half day) on engineering level Topics which need urgent progress – Mapping – Data content – Simulation –... Next big dead line: link speed test (end of this year) – Need to agree on date
