Accelerator Division Goals - Bob Mau

There are three main goals for the Accelerator Division and ultimately for the Operations Department.

1.    Integrated Luminosity
2.    Integrated Beam to Booster Neutrino Beam
3.    Integrated Beam to NuMI

The following three charts show how we are doing. The blue and red lines show different levels of achievement. The blue line represents our minimum level of achievement. The red line represents an achievement that could be within our grasp, but is very optimistic.

You can find these charts yourself by going to the Accelerator web page, Other Stuff, Run Coordinator, and you will find the Current Operational Data Plots: or you could just go here: http://www-runco.fnal.gov/.

Integrated Luminosity Chart

On May 9th we crossed the blue line.

The blue line is on the X-axis of the chart, so it wasn't hard to cross. The reason the BNB line is so far beyond the red line is due to the extra beam they have received because of NuMI problems.

Crossing the blue line would seem pretty difficult at this time, but it is possible if we can maximize their up time, once they finally get back up and running. However, it is important for Operations to try.

Where did the red and blue lines come from?
In 2006, the Accelerator Division created a model, from 16 input parameters, to predict weekly-integrated luminosity, which was then extended to cover a three-year period. This model predicted the integrated luminosity for 2007 to be approximately 1363 pb-1 for stores that lasted 20.6 hours. The actual delivered luminosity was 1311 pb-1.

Five scenarios were made using three stacking profiles with peak rates of 22, 25, and 27 E10 per hour. It was assumed that the stores would last 21 hours and the antiprotons would come from six transfers between the stores. The scenarios were rated from more pessimistic to more optimistic.

Scenario I: Stacking profile 1 (22E10) and a 100 store hours a week. The input parameters were consistent with 2007. Integrated luminosity should equal 2619 pb-1.

Scenario II: Stacking profile 2 (25E10) and a 105 store hours a week. The input parameters included more protons per bunch, a better transfer efficiency between the Recycler and the TeV, and a better timeline utilization factor. Total integrated luminosity should equal 3044 pb-1.

Scenario III: Stacking profile 2 (25E10) and a 115 store hours a week. The input parameters assumed a Recycler/TeV transfer efficiency greater than Scenario II with a shorter transfer time, and a 1% better TeV lifetime. Total integrated luminosity should equal 3338 pb-1.

Scenario IV: Stacking profile 3 (27E10) and a 120 store hours a week. The input parameters assumed a 2% better luminosity density, and a timeline utilization factor that is better than Scenario III. Total integrated luminosity should equal 3545 pb-1.

Scenario V: Identical to Scenario IV, but uses stores of 18 hours where the peak stacking rate is 27E10. Total integrated luminosity should equal 3709 pb-1.

The Blue line is Scenario I.

The Red line is Scenario IV.

Blues On The Fox - Wally Kissel

You say you got the blues and you don't know how to pay those dues? On June 13 and 14, if you head out to downtown Aurora, you might find a bunch of people with the same problem. And what is it that's getting you down? You just didn't get enough Blues at the Chicago Blues EST?

This will solve all of your problems:

Friday, June 13
6:45 PM – Eddy "The Chief" Clearwater
8:30 PM – Elvin Bishop

Saturday, June 14
3:00 PM – Hix Bros Junior All-Stars
4:00 PM – Corey Harris
5:30 PM – Bettye LaVette
7:00 PM – Macia Ball
8:30 PM – Kenny Wayne Shepherd

The festival is free. There will be food and drink to buy.

Vacation - John Crawford

As you all know, part of the Laboratory's cost reduction scheme for fiscal year 2008 requires employees to use all vacation time that they accrue between the end of January, 2008 and the end of September, 2008.

You all do know this, don't you?

What you may not know is that there is a cutoff date to use that vacation so that it will count against your accrual. That date is Sunday, September 21, 2008; any vacation used between September 22 and September 30 will not count against your accrued vacation and you will lose that excess vacation time. The September 21 date applies to both weekly and monthly employees.

Furloughs, Vacations, and Fermilab Rulers

I have the shift schedule posted through the beginning of July. I have removed all of the furloughs (F's). Thanks for working with us over the past 4 months of furloughs. It made a tough situation easier to get through. We still have the problem of taking vacation before the end of the fiscal year. The crews have been getting pretty light on some shifts. Please try to give us as much notice as possible. Shift trades should also be considered. The Day Shifts continue to be light, so if you are on backup, make sure you attend briefing and check in with the Crew Chief.

The effort reports and leave sheets are getting easier again. Please remember to fill out your effort reports, leave sheets, and dosimeter readings.

I am sure you have all read this newsletter thoroughly and have memorized the email you received from Bob. I would like to give away some Fermilab rulers. The first 5 people that email me the date you must take your vacation by (or lose it) will get a Fermilab ruler. (Hint: September xx, 2008) Only one guess per Operator to avoid getting 30 emails from each of you.

Good Luck!
