| 2740 | 22.0 | 430 | Abort | 7.2 | 140 | Sequencer failed after 5th pbar shot;
Ops error during re-start of sequencer;
25 extra minutes on Helix @ 150GeV |
| 2746 | - | 0 | Quench | - | 123 | TeV experts left tunes at end of squeeze at incorrect values;
Tried to tune down losses; result in quench |
| 2751 | - | 0 | Quench | - | 104 | LBSEQ wrong value caught by sequencer;
Ops restarted sequencer at wrong command with still wrong LBSEQ value |

## Integrated Luminosity for the Week (2.5 days)

**Integrated Luminosity for the Week (2.5 days)**

- Experiment Access

- Abort: RF Sum bit but not it

- Abort: Frig excursion

***Some other stuff did/didn’t happen ***
***beyond Tuesday 1pm last week***

## List of Problems

- Collider
- TeV expert error; Ops error; Frig excursion; Abort on RF sum bit (but not sure what really happened); CDF pot ”in”
- TeV
- Wet engines; Lost communication with frig VMEs; Locked at 90GeV; C3 CVT; Feeder 23 fault; D3 VCB; Switch to other power supplies; Phantom B2 ground fault; A3 power supply smoking; knife switches; A2-A3 line driver; F4 turbo pump failure; CHL distribution box failure
- Main Injector
- MIRF12 PA; Bad Q637; MECAR and bad permit module; Q703 power supply; MI10 PS loop; LCW conductivity; MI40 AC failure; MIRF15
- Pbar
- D:IKIK mis-firing; DRF2 timing; DRF1-5 dead; Clearing Electrodes and emittance growth; losing ~30mA (x2); D:V406 read back; LCW temperature
- Proton Source
- QPS307 trips; V803 over-heating; BRF9 trips; MH2; Booster ion pumps/vacuum; MKS05 PFN (x2); Flood of pre-acc; Source dead (x3); KRF4 trigger circuit; KRF4 PS; KRF5 PS; Linac tilts
- Other
- VME reboots; ComEd power glitch; Thunderstorms

## TeV Studies

- Mostly Beam Maintenance
- Parse of squeeze
- Commissioning of instrument to measure chromoticities and head-tail instabilities
- Alternative skew quad settings
- Beam lifetime as a function of tunes
- Dynamic aperture and centering in S6 elements (feed-downs)
- Checkout after switch of power supplies

## Brief Summary

- The week
- A very long weekend
- Two aborted stores

- 42hrs of stores
- FY03 total is 179.4pb-1; 7 weeks to shutdown
- Need 6.5pb-1/week
- Goal for this week
