List of Sequencer changes • Add line to select 3X3 store • Disable PBJ script (Done inside script) • Disable Adjust LB_tune (Done inside script) • Disable Adjust tunes script (Done inside script) • Change synch lite spec from 4 to 5 (prepare to ramp cmd 4) • Disable synch lite spec 0 (Rem Halo cmd 34 and 41) • Modified Remove Halo aggregate with a special instruct • Modified collimator sequence map • Inject commands driven on V:3X3 state device. • Disable Web log chapter (Decelerate cmd 59)???

  3. Command to Select 3X3 Has to be enabled at start of week. Will execute only If TEVMOD is HEP mode

  4. Inject Final Proton Command Used by TLG to select number of batches. (Normally set by Coalescing Command.) Will skip if V:3X3 is not 2 Will skip if V:3X3 is 2

  5. Inject Pbar Command Will skip if V:3X3 is not 2 Will skip if V:3X3 is 2

  6. Remove Halo Aggregate New tevcol command Will tell operator to jump to new point in sequence Will only execute if V:3X3 is 2 Truncate command will stop sequence so operator can jump to retract section

  7. Tev col 8 setup

  8. Sequence map for tev col 8 (normally all zeros)

  10. Topics of concern • Single bunch Injection • Protons just set G:NBTEV to 1 (this is buried in a coalesce command) • Pbars: RR guys make it happen • Qualifier setup • Set T:NBATCH • Inject command • TEL setup? • Longitudinal Damper (OK as is) • Scraping • No Collimators in at flattop (Done inside script) • Change $DB or $CF setup? • Energy Scan stores in 2.5 weeks (this will be hard – need everyone)
