Subject: Run-4: experimental backgrounds


> Dear all,
>
> since we are able to deliver reasonable high luminosities
> (last night had 3 stores with average rates of 2.5kHz),
> it is time to have a closer look at backgrounds.
>
> Thus we would like from every experiment initially ONE
> background signal that MCR needs to MINIMIZE.
>
> This signal can be constructed from several signals that are
> specific to every experiment, and should be normalized with
> the luminosity. Last run we had, if I remember correctly,
> signals that were considered good, when their value was approximately
> 100. We should probably discuss this in Monday's scheduling meeting.

> On Saturday, Mike Brennan will work on making the storage
> system operational. Rebucketing has been demonstrated in Yellow
> (with the old technique), and Blue (with a new technique). If this
> is suceesful, we can start the Physics Run on Monday after
> the access. We have a procedure for debunched beam, and will deal
> with the STAR magnet as soon as the magnet is operational.
