  1. EASY6000 A step forward for HEP electronics Viareggio, 14 June 2019

  2. New requirements in HL-LHC

  3. EASY6000 concept • Extremely flexible architecture, allowing more configurations than the previous generation • New harsh converters for Very Hostile Area (>200 Gy) to be placed closer to the detector (~m) optimizing cable power loss • New faster connection to DCS thanks to the brand new R6060 branch controller with Gb Ethernet • New faster connection to the EASY remote boards thanks (CAN for back-compatibility, SFP+ for high-bandwidth, RS-485 for robustness and easy implementation. • More power thanks to a 300V bulk power line from service to experimental caverns: 6x higher voltage -> 6x less current -> much less cable area to have the same power efficiency or much better power efficiency keeping the same cables Distance 0m ~100-120m ~150-170m up to 200m

  5. Path to EASY6000 • The EASY6001 BRIC is the first module developed to survive to the end of HL-LHC at 200 Gy and 0.5 T and designed for operation with CERN DC-DC POL • Water cooled is a DC-DC converter from 300 V to 10 V capable of delivering more than 1.6 kW in a small format (20 x 20 x 10 cm) • It is going to power ATLAS NSW sub-detector • Very important test for CAEN technological capabilities and reliability

  6. Back-up Slides

  7. EASY3000/4000 • The current system was built as a hostile area extension of the SY1527 (now SY4527) • It has done a great job but in the years some area of improvements have been identified: • Communication speed on very large installations (scalability) • High-power density solutions • Starting price for small setups

  8. EASY6000 control EASY6000 • To tackle the communication bottleneck we are developing a new branch controller that, rather than being installed within the CAEN SY4(5)527, will be standalone • R6060 • The new controller will be placed in service cavern/control room and it will provide 200W (twice the A1676A) service power and guarantee a fast and responsive connection • More racks will be controlled using less hardware and space in the service caverns • The new controller will allow the remote communication up to ~150m  using commonly deployed communication cables (i.e. CAT5 twisted pairs). EASY6000 EASY6000 EASY6000 EASY6000 EASY6000

  9. EASY6000 power • The independent service power will arrive directly from the new branch controller at 48 V • The external AC/DC power source at 300 V (100V/200V options under evaluation) minimizes cable losses to bring the necessary power from the service cavern to the experimental cavern: • Hp: 3kW to be delivered @48V (~60A) via AWG0000(Ø 11.7mm) 100m(x2) cable, ~115W power loss • Hp: 3kW to be delivered @300V (10A) via AWG9(Ø 2.9mm) 100m(x2) cable, ~100W power loss only (95% power efficiency) • This choice will help the maintenance of the bulk AC-DC converters thanks to their location in safe area.

  10. EASY6000 hostile area • A new range of advanced boards is being designed to cover the experimental needs of HL-LHC • All boards must survive the harsher conditions of the experimental caverns during HL: • 20 kRadtotal dose (200 Gy) • 5 x 1012 n/cm2 (1 MeVEq.) • 1 x 1012 p/cm2 (>20 MeV) • We resolved to test the boards at: • 40 kRadtotal dose (400 Gy) • 6 x 1012 n/cm2(1 MeV Eq.) • 2 x 1012 p/cm2(>20 MeV) • Special needs above these will be address with special developments

  11. EASY6000 family • The boards will be adaptable via a back/interface-board to various cable types • The back/interface-board will ensure an easy and fast swap between boards, so the maintenance time spent in Controlled Radiation Areas is minimal according to the ALARA principles • The safety of the system is granted thanks to many precautions: • Careful component and system tests in hostile environment (several MOSFETs, BJTs, PWM ICs, analog ICs, Vref, Opamp, Data converters, Drivers,… tested during last 3 years in H.E.) • Robustness of the most delicate circuits ensured by design (component de-rating, selection of best circuit topologies, proper devices biasing strategy,…) • Redundancies where needed (both in HW, FW and SW) • Advanced Diagnostics: sensors and on-board algorithms to predict and avoid failures (thanks to the ongoing PRIMIS R&D project)

  12. EASY6000 Boards LayoutMain Option • 19” 6U crate • 20 slots available • 5U backboards with 1U for connections/fuses • Power bus at 300 V • 1 removable crate controller

  14. EASY6000 LV boards range (in development) One of the most used load for HL projects is expected to be the feast DCDC developed by CERN, therefore CAEN is designing LV boards for it: • LV between 9-12 V with V_max at 14 V • No sense wire but well define ramp UP/DOWN to operate with DC-DC ON-OFF • High power density 1) High power: 720 W per board -> 8 kW per crate (IND. CHANNELS) • A6606 720 W (9-12V) per board with 6 independent channels 2) High channel density: 12 channels in a double EASY6000 slot (DISTRIBUTOR) • A6601 250 W (9-12V) per board 12 channels (20W/ch roughly) (just monitored only 1 VSet per board) 3) Coming soon: a board for serial powering configurations is under development as well

  15. EASY6000 HV boards range (in development) Many of the new detectors are going to be based on silicon sensor and we are developing two boards for the bias of these sensors in high radiation environment, these will need higher bias voltage w.r.t. current sensors and high currents towards the end of their life. We are planning two boards to fulfill these requirements: • High density board with 12 HV ch • A6701 12 ch at 1 kV @ 20 mA • High power board  with 100 W per channel • A6706 6 ch at 1 kV @ 100 mA per channel

  16. EASY3000 – Updates & Upgrades • EASY3000 boards will be maintained as long as possible, no discontinuation strategy planned • The EASY3000 will also benefit from the new R6060 (new branch controller) • Replacement boards for the A3xxx series and other CAEN systems currently in use, will be developed according to experiments needs/requests, according to first-come first-served criteria and project size:  • New HV board(s) to improve the A3512, A3535, A3540,…? • New LV board(s) to replace the A3009, A3016,….? • We are currently involved with CMS-ECAL and CMS-DT to re-design the replacements of the existing solutions with new projects. • A global coordination of the needs would be necessary
