The back door web access requires a some extra knowledge of your system.
Ill get to how in a minute.

First to get to the web archiver, go to the star home page
www.star.bnl.gov
Then go to group documents, then to star controls link (ctl), and then to
the Archiver link, and then to the Slow Controls Archiver link.
(if figured directions from the star home page would be useful)
All this takes you to:

http://sc3.starp.bnl.gov/archive/star/project1A.html

When I get the time and the access, Ill add a link here for TOF. From the
TOF page ill have links to your subsystems:
TOFr Gas, TOFr HV, & TOFp HV.

Until then you have to get to your data through the back door.

The back door method is to click any link on this page (try Cathode, its a
one jump link to where you need to be). It will take you to a screen with
the following sections:

Channel info:
        A bunch of epics channel info
Pattern:
Names:
        A bunch of epics channel names
and some other stuff.

The point of having your own links to a page like this is it will auto
fill in the channel names appropriate to the subsystem your interested in.
Since this page isn't made yet, you just need to change the names in the
'names:' box to the epics names corresponding to the data you want.
(and delete the names you dont want)

The epics names for your data are:
        for TOFp:
                TOFp:cell_# cell's electronic id
                TOFp:volt_# real voltage
                TOFp:set_# demand voltage
 ( you need to replace the # sign with a number between 0-40 )
                TOFp:HV_br#
 ( you need to replace the # sign with the appropriate branch number)
        for TOFr HV:
                TOFr:Vread_#
                TOFr:Vset_#
                TOFr:Iread_#
                TOFr:Imax_#
 ( you need to replace the # sign with a number 0 - 3 )
 ( 0 = A-, 1 = A+, 2 = B-, 3 = B+ )
        for TOFr GAS:
                TOFgas:Freon
                TOFgas:Isobutane
                TOFgas:SF6
                TOFgas:iso_ratio
                TOFgas:sf6_ratio

after you type in up to 10 channels that you want to look at, change the
start and end times to an appropriate interval (something current), and
hit plot. It will plot the stuff for you. You can also experiment with
the other command buttons there.

any questions email me,

steve
