## Quench Protection for IR Quads

- Three new Quench Protection Monitors Required
- Hardware the same as B0/D0 QPMs
- VME64  crate
- Motorola Processor board running VxWorks real time operating system
- Digital  and Analog I/O on PCI Mezzanine cards
-  Connections made through Transition Modules (Universal Breakout Boards)
- Software modifications to reflect different number of circuits, voltage taps and power leads
- Quench Detection Algorithm, Power Leads monitoring algorithm, Circular Buffer size and structure, etc. remains the same as in Tevatron and B0/D0 QPMs
- Application program presently used to interface B0/D0 QPMs will be extended to include C0, C1 and B4 QPMs

## Quench Protection for IR Quads– Cont.

- Uninterruptable Power Supplies
- Same as used in the Tevatron
- Heater Firing Units
- Q6 and Q7 will use Tevatron Heater Firing Units
- Q1-Q5 will require new Heater Firing Units
- LHC voltage and capacitance
- Larger power supply to charge capacitor bank faster than LHC
- Tevatron style QPM interface
- Voltage to Frequency Convertors
- Same design as used in the Tevatron
- Cabling
- Voltage taps and Heater cables

## Tevatron QPM Modifications

- Minor Changes required to the B4 and C1 Tevatron Quench Protection Monitors
- One additional Heater Firing Unit
- High Temperature Superconducting Power Leads added
- Dipoles re-arranged

## Organization and Management

## Schedule

- Controls work will begin FY07  to help match the funding profile
- Effort is spread over multiple departments and groups and will not be a large burden on any particular group or person

## Schedule                         WBS 2.5

## Labor Profile by Fiscal Year (FTE’s)      WBS 2.5

## Total Obligation Profile by Fiscal Year    WBS 2.5

## Construction Obligation Breakdown         WBS 2.5

## Risk Analysis

- Mitigation:
- Will compare the two halves of the magnet.   This has been done in the experimental areas.
- Included a large contingency for this item

- Risk:
- Q6 and Q7 paucity of voltage taps
- Using existing magnets with only one center tap in single magnet circuits
- HFU cost
- LHC HFU costs are hard to apply as they made 6500 units and had them assembled in India

## Summary

- All required hardware is same as Tevatron designs except for LHC style heater firing units.
- Software changes are well understood and resources will be available
