BLM FOR THE INJECTORS PROJECT LINAC4 & PSB Beam Instrumentation Review – 18/10/2011 Christos Zamantzas

Introduction This project has undertaken the task to develop up-to-date Beam Loss Monitoring Systems for the Injectors. Mainly, Build a generic, highly configurable and high-performing system Acquisition part to accept any monitor type Use reprogrammable parts to target all injectors’ requirements Team members: BI/BL: M. Alsdorf, B. Dehning, E. Effinger, J. Emery, G. Venturini, W. Vigano, C. Zamantzas BI/SW: S. Jackson, L. Jensen LINAC4 Review – 18/10/2011

General Information Useful information on the LINAC4 and PSB requirements can be found in the following links: Beam Interlock Specifications for LINAC4, Transfer Lines and PS Booster with LINAC4 [ Notes on the Beam Loss Monitoring System for LINAC4 and PSB [link]link  Description of all important info, specific implementations, etc  Documents under preparation.  Meeting notes Summary table of requirements [link]link  Result from discussions the BL and SW sections had with OP LINAC4 Review – 18/10/2011

Acquisition & Processing Synchronisation of acquisitions is required with the start of the cycle to  Perform calculation of integration periods and  Schedule comparisons with their corresponding threshold values. Synchronisation to be achieved by  Use an event received through the timing system.  Dedicated timing card with broadcast in the backplane.  Sync will be done at the processing level (i.e. 2 samples jitter between cards). Up to 4 integration periods:  2  s, 400  s, 1 ms and 1.2 s (full cycle)  Log maximum values recorded for each in the cycle  Log 1.2 s value for ambient radiation measurement LINAC4 Review – 18/10/2011

Threshold Comparisons The threshold values will need to be unique per channel:  Each card will process 8 channels The threshold values will need to be unique per user:  The information of the current user has to be obtained from the telegram per cycle -> dedicated timing card  Memory for 32 users should be reserved. Two integration periods, 2  s and 1.2 s, will be checked against their threshold values:  2 threshold values, one for each of the integration periods.  In the case the measured values exceed those the beam permit signal will be removed for all users and until operator acknowledges. Two integration periods will be checked for repeated over threshold function (might be implemented in SW)  An additional 2 threshold values for the same integration periods (i.e. 2  s and 1.2 s) will also be required.  In the case they are found to over threshold repeatedly n times it will be required to block this user’s injections only until operator acknowledges.  The repeat value n will be settable per monitor in the range of 1 to 16. LINAC4 Review – 18/10/2011

Beam Permit Logic System has to block injections  i.e. “remove permit” if losses over threshold System has to remember if the user is allowed to have beam  i.e. “give permit” if previous cycle for the user was ok (or errors cleared) The Beam Interlock Controller will be configured in the “Non-latch” mode.  i.e. the BLM system will need to follow timing and notify in advance. The maximum latency (from measurement to output) should be kept as small as possible.  The target for the first integration period is ~ 5 μs. Only data from the current cycle need to be considered.  Timing in the electronics essential (i.e. possible failure mode) LINAC4 Review – 18/10/2011

SYSTEM OVERVIEW

System Architecture LINAC4 Review – 18/10/2011

Acquisition Crate 12 3D model of the Acquisition Crate Acquisition cards (BLEDP) Main panel LEDs Power switch Ref. Input Control Unit Later version w/ advanced remote functions by William Vigano LINAC4 Review – 18/10/2011

Acquisition principle (ACFC & DADC) The input channel circuit is able to measure current input from 10pA to 200mA. The measurement of the current input is performed by two different techniques: 1)Advanced Current to Frequency Converter (ACFC) used in the range 10pA to 30mA 2)Direct ADC acquisition (DADC) used in the range 20.3µA to 200mA 13 No gain change required: The switch between the 2 ranges is managed by the FPGA. If the maximum ACFC counts is reached, the FPGA switches the circuit to the DADC mode. When the value of the DADC falls below a threshold, the FPGA switches the circuit to the ACFC mode. by William Vigano LINAC4 Review – 18/10/2011
