3. DEVELOPMENT 28/08/2015

4. Development Using the prototype installations at PSB and PS we were able to: identify and solve issues in the analogue circuitry of the acquisition card in terms of leakage current, offset, temperature dependence etc.  recently all modules have been sent back to the manufacturer and modified the input stage. develop and validate the firmware and software  recently updated the firmware to control better the start-up procedure of the analogue circuitry.  recently updated the FESA class to provide both raw and normalised to Gy/s measurements. develop and test in real conditions the continuous connectivity check  under development a continuous quality check of the complete chain from the detector to the processing electronics. Still several parts need to be addressed in the firmware: most notably: loading of settings/thresholds, system status information and interlocking. christos.zamantzas@cern.ch428/08/2015

5. Prototype installation PSB One complete rack with all electronics has been installed  covers all L2 locations in the PSB ring (32 ch.) and  some channels in 4L1 hotspot (4 ch.) Advanced versions of Firmware and Software available. Direct Ethernet connection to each acquisition module available for detailed analysis and debugging.  2 μs samples continuously Through FESA class, system provides the ‘evolution’ data synchronised with the basic period.  1 ms samples during beam presence Have already been used in a couple of MDs. OP has a first version of its fixed display. christos.zamantzas@cern.ch528/08/2015

6. LINAC4 28/08/2015

7. LINAC4 1/3 Detectors have been defined and available  Will use LHC type ICs,  Exception at 50 MeV to be equipped with a Diamond Supports for the machine line (+ some spare) have been designed and produced  Some have already been installed  The remaining are scheduled from Nov. 2015  Found solution for the non-conformity issue not seen earlier during integration check Supports for the transfer line are pending  Meeting in September with Alessandra and the integration team to clarify the position of channels  Based on that outcome, we will know if we can re-use the current support design or we will need a new one. christos.zamantzas@cern.ch728/08/2015

8. LINAC4 2/3 Majority of the cables have been installed (CKB50 type)  All cables in the tunnel are enclosed in a metallic tray  Missing installation of one channel  issue with crossing a wall  waiting for decision from EN/EL-BE/OP Assembly of connectors of signal cables  Not done - we need first the supports installed  this blocks us also from installing all other electronics in the rack.  EN/EL agreed to go for partial assembly  first assemble all connectors in the surface and  then batches in the tunnel following the installation. christos.zamantzas@cern.ch828/08/2015

9. LINAC4 3/3 All electronics produced, tested and ready  Installation planned for November Firmware and Software  Ready for measurements  Interlocking abilities Q3 2016 Specifications agreed Budget OK christos.zamantzas@cern.ch928/08/2015

10. PSB 28/08/2015

11. PSB 1/2 Detectors:  75 ICs and 32 FICs - all procured.  8 Diamonds - to be procured this year.  also spare detectors for all types will be available Cabling list request have been updated with  new channels and spare cables for all locations  Ring: 32 ch. w/ FIC, TL: 43 ch. w/ IC and BI: 8 ch. W Diamonds  Spare channels: 16 in the Ring and 7 in the Transfer Lines Support’s design for Ring L3 positions (FICs) is complete  Waiting for integration team to give also the ok before we go into production.  A prototype will be tested in the machine next week. Supports for the new injection section (ICs and Diamonds) is complete  Design will circulate for approval soon. Supports design for all remaining transfer line detectors (ICs) has not started  Next week first try in collecting all data/photos.  We expect it to be very complicated due to topology and space. christos.zamantzas@cern.ch1128/08/2015

12. PSB Supports for FIC christos.zamantzas@cern.ch1228/08/2015

13. PSB Supports for new Injection line christos.zamantzas@cern.ch1328/08/2015

14. PSB 2/2 Three new racks have been assigned positions and requested for installation. All electronics for the ring and BI line produced, tested and ready for installation Electronic modules for the ejection lines in planned for the next production to start at Q4 2016. Specifications are agreed. Defined and agreed naming convention for all channels with quality assurance team  with the exception of Observation system Budget is OK. christos.zamantzas@cern.ch1428/08/2015

19. PS 2/3 Specifications:  After providing additional information to Rende on the specifications, he ‘approves’ current proposal with some modifications.  Will meet again after OP’s internal discussion.  Specifically for the OASIS connection  in the legacy system the signal of all ACEMs is split and one part is send to OASIS acquisition cards and the other to the on-board integrators.  proposal is in the future to provide 1 ms digital samples directly to an OASIS class.  Specifications document will be amended and redistributed christos.zamantzas@cern.ch1928/08/2015
