## Getting to 5.3.2: Recent Simplified History

- Main change in 5.3.1  5.3.2 was originally the beamlines fix – a production issue
- Part I: Material overlap under misalignment
- L00/Beampipe containment volume overlap
- Some passive material (rails) moved in strange ways
- Part II: Joao discovered/reported serious problems
- Beampipe was missing
- L00/SVX misalignment was not happening
- Intense effort launched & organized by Young-Kee
- Beampipe put back in; misalignment switches fixed
- Rails, bulkhead ledges, and inner screen geometry problems fixed
- New crashing problem (fixed yesterday?)
- 5.3.2 frozen and released today?

## Summary of Some Recent Changes

- From Matt H. (2004.06.17):
- “
**Changed** the types of **geometric transformations** used to place the **L00 rails** to a set that commute with each other. Changed the default placement after looking at the construction diagrams.
**Included code** to **align all positive bulkhead components** using the space frame and barrel alignment constants.
**Adjusted** default **rail and barrel positions** to **eliminate** most **overlaps**. In both cases I moved the components inward. 200um for the bulkheads and 1mm for the rails. I don't think this will affect the physics purpose of the passive geometry. That this was necessary means that our current active sensor silicon alignment is slightly unphysical.

## Announcement: Run-Dependence in MC

- Note that for 5.3.2, there are fundamental changes to the way MC production will be done.
- See talk later in this meeting on _MC Run Dependence_.
- Merging of _minbias events_ to simulate multiple interactions will also be available (used by EWK group), but will **not** become the default for now.
- A lot of work has gone into this improvement to the sophistication of our MC.

## MC Production Schedule

- Severely constrained by timing of 5.3.2 readiness.
- 6 weeks prior to ICHEP: end June.
- Metric: 11s / ttbar event / 2.4 GHz
- Time for 75M events @ 1 GHz: ~2 Gigaseconds
- CPU needs to end of June: ~1.7 THz
- Schedule is extremely tight:
- Use Toronto (BigMac) / Alberta (Thor) / WestGRID
- Use of DCAF resources is essential
- Physics groups encouraged to request minimum sample sizes
- Must work together if any 5.3.2 MC is to be ready for summer
