## Instrumentation & Communication Overview

- Instruments
- Environmental, such as
- Temperature
- Pressure
- Humidity
- Synchronous with the beam, such as
- Horn magnetic field: “Bdot”
- Beam on target: Budal Monitor
- Beam/Horn alignment: Beam Loss Monitor (BLM)
- Timing: Horn current relative to Beam
- Motion Control & Readback
- Horn 1 angle & transverse
- Baffle/Target angle & transverse
- Baffle/Target longitudinal

## Instrumentation & Communication Overview

- Communication with ACNET
- ACNET Input Sources
- Analog Entry Box (AEB)  MADC  CAMAC
- Environmental sensors (temperatures, pressures...)
- Beam Permit (AEB Process Channel Interface Permit)
- 	(15 Hz sampling)
- Beam-Synchronous signals (Bdot, BLM, ...)
- PLC ethernet front-end processor ACNET
- A less expensive option to condition thermocouple signals
- 	(described in Andy Stefanik’s talk)
- Motor Control: ACNET InputethernetACSmotor
- Motion Control Position readback  ACNET
- Alarms
- Limits entered into database

## Hardware Safety

- Motion Interlock
- Prevent Target from colliding with Horn 1
- Target range: 20cm vertical, 250 cm longitudinal
- Disable transverse motion of target and horn 1 when:
- Target is not at beam height
- Target is moved into horn 1 beyond a critical point
- 2.7 mm clearance at max insertion if centered
- Beam Permit
- Beam permit dropped if values are outside limits
- Baffle Temperatures
- Air Supply Temperature
- Air Supply Fan Differential Pressure

## Motor Control 

- VME Crate*
- MVME Processor* with ethernet connection to ACNET
- VME Carrier Board with 5 IP Stepper Motor Modules
- Each Stepper Module handles 2 Motors & 4 Limit Switches
- Stepper module communicates with ACS motor modules
- VME Carrier Board with 1 IP A/D Module
- LVDT readback
- ACS Crates
- Two crates & one power supply
- 9 ACS motor modules
- Cables & connectors
- 	*supplied by controls dept.

## Cables

- In high radiation area (beam line & beam devices)
- Radiation-hard cable routed up to patch panels on top of modules
- Budal (Tgt current), Baffle, Bdot, Baffle & Horn Temperatures
- Rad-hard cable: MgO insulation, two conductors in a metal sheath
- Custom-fabricated connector mounts
- Connect beamline cables with module “penetration” cables
- BLM HV cable: must withstand several kV
- “Home-made” coaxial cable with ceramic insulators
- Straight shot...no bends
- Patch panels  PS Room
- Patch panels for rad-hard beamline cables conventional cables
- Motors, LVDTs, sense switches, some thermocouples...                     conventional cables
- All signals to Power Supply Room via RAW Room

## Timing

- Ensure that horn pulse peaks in time with beam spill
- Goal: within 10 μs (150 μs mismatch  1% lower field)
- Budal or BLM signal for beam timing
- BLM will probably be saturated
- Bdot or PS transducer for horn pulse timing
- Horn pulse is ~2 ms long half-sine wave
- Timing Hardware: to be designed
- Custom made TDC with ~200 usec range; 0-10V AEB
- Alarm issued if timing outside limits
