Ongoing BE-BI developments going to be exposed to radiation Radiation working Group meeting (26 May 2016) Andrea Boccardi, on behalf of BE-BI

MOPOS SPS new Beam Position Monitors Analogue (based on logarithmic amplifiers) and Digital (Based on the GEFE) front-ends exposed to radiation Expected dose up to 100Gy/yr in few points but… See Corinna’s presentation Tests being performed at the moment on a full GEFE in CHARM Diode ORbit (DOR) extension to be designed Installation expected for LS2

CPS and SPS wire scanners Replacement of the wire scanner based emittance meters for the PSC and SPS Design based on the QIE12 Integrator designed in Fermilab for calorimeters (kGy range) and the GEFE (to be confirmed after the radiation tests) Expected doses: up to 100Gy/yr (shielding might be required) Installation: LS2 Responsible: Bernd Dehning

SPS and LHC BLM New BLM front end based on an ASIC developed in collaboration with PH- ESE Project fully based on radiation tolerant by design active components (VTRx, GBTx…) Installation for SPS and LHC foreseen for LS3 (only few locations for the LHC) ASIC still under development: tests to be finalized Expected radiation levels: 500kGy for the LHC, to be defined for the SPS Project responsible: Bernd Dehning

PS BGI Beam Gas Ionization based profile monitor for the measure of the emittance in the PS The design is in its starting phase and will be based on PH-ESE ASICS for the radiation tolerant front-end For the first tests the digital FE will be based on the GEFE In its final implementation the front-end will be based on the Low Power GBTx or on the PONG (the GEFE doesn’t have enough BW and its tolerance to radiation not enough due to the presence of the FPGA) Prototypes to be installed sometimes in 2017 Responsibles: James Storey

Diamond BLM Diamond detectors based BLM system COTS amplifiers from CVTech, not qualified but used in ATLAS since few years (accumulated dose till now ~500kGy) Very few systems to be installed for the moment and not critical Electronics replaceable in case of problems Project in R&D stage Responsible: Bernd Dehning

BTV Beam TV Responsible: Stephane Burger Radiation tolerant cameras (30kGy – 50kGy) Stephane Burger is following the development/study of Elisa Guillermain The project is at an embryonal stage Installation for AFTER LS2 Cheap expendable cameras: CMOS sensor with minimal surrounding electronics They are supposed to replaced the currently used CCD that will get out of production in 2019 Project not started yet Optical Fibre bundle for the transport of the image away from a radiation harsh environment To be possibly used in conjunction with the cheap CMOS cameras Responsible: Stephane Burger

TT2 Wideband Electrostatic PU Beam Position Monitor for TT2 The pre-amplifier is mounted directly on the pick up (PU) body (BW few KHz- 400MHz) Designed and installed in the 90’ with an expected life time of 3 years for the measured radiation level of 1kGy/yr, but with the advent of CNGS type beams the life time of the electronics was drastically reduced to about 4 months (last measure for one of the PU was 10kGy/yr) Only 4 pre-amp are in the hot region, but is more and more probable the need of a new design Responsible: : Jeroen Belleman

PS and SPS eAs Profile monitor Scintillating fibres based profile monitor for the experimental areas The new system will replace the aging one already installed Solutions and readout electronics still being studied but for the first prototype (not exposed to radiation) Photodetector readout based on a rad hard ASIC, the SPACIROC The discriminator for the signals from the photomultiplier will be the NINO developed at CERN An FPGA will be required for the processing of the signals from those 2 ASICs External memory (SRAM) is foreseen as processing support and local data storing Data transmission over optical fibre

Close to the beam but ‘safe’

Linac3->LEIR BPM Beam Position Monitors for the transfer line from Linac3 to LEIR Amplifier close to the beam (<10cm), digitalization and processing not exposed to radiation Expected levels of radiation: Unknown Installation foreseen for YETS 2016 Project in its initial phases Responsibles: Michele Bozzolan, Lars Soby

ELENA BPM Beam Position Monitors for ELENA (antiproton decelerator) Analogue front end at few centimetres from the beam pipe Expected level of radiation: unknown Installation foreseen for June-July 2016 Project design finished Responsible: Lars Soby

Laser Emittance Meter Laser scan based emittance meter for Linac4 Electronics installed about 5m from the beam line (~50Gy during the lifetime of the instrument) Project in collaboration with Royal Holloway (UK) Development just starting Translation stages for the optics and the detector (diamond) at 30cm from the beam (~500Gy total accumulated dose foreseen) Responsible: Thomas Hofmann

Step motors’ control Control for motors close to the beam The driver stages are commercial as well as the power supplies and have not been qualified The digital control is based on the GEFE, but for the moment is foreseen to install the systems in US and UAs. If possible, after qualification, some systems could be installed in the tunnel (BSRT optics control) Project in course of development Responsible: Felix Arnold, Enrico Bravin
