Meeting
Agenda
23 March
2004
In
attendance: J. Nelson (notetaker), J.
Frisch, R. Fuller, R. Hall, J. Rock, R. Chestnut
Timetable
for Checkout
We’re expecting hardware
Friday. On Monday get signals and
triggers wired to hardware. Morning of the 30th – realistic signals everywhere –
start software checkout.
Calibration stuff – I&Q->A&P will be done offline. ADC volts to power calibration … Middle of next week
probably.
Processing
Slow
archiver?
Janice and Bob will see if
WFM acquisition speed has improved and measure it.
Secret
Decoder Ring
Need to expand Steve’s
spreadsheet of Channel map to include Base Addresses (full 32-bit VME address)
for modules and slot locations. (Judy is gonna help out with this.)
SLED FDBK
through SCP slow feedback
(still true) Ed
did a wonderful job creating this, but unfortunately we haven’t had a chance to
test it yet (hardware problems/tests). 4/1st probably.
Janice
will send Ed a warning email that this is coming soon.
SIS
waveforms archived every hour (plus on change)
(still true) We do
want this and around early April.
Database
and Displays
Judy has
booted in new LLRF PVs – PWRs and ENs and WFs.
Display
changes are underway. Joe points out
lower level displays are needed sooner – early next week, than those showing
PWRs and things like that.
A&P much
lower priority. (until we can watch SISes without
archiving the data)
Processing
Loop status
Processing
Janice provided
to Ron (and at the end of these minutes) the equations for missing energy
needed.
macnair
module support of aes
(no new news until proc loop done)Basic database is there and
works now in TR09 and TR06. (yeah) Then Ron has a
bit more database stuff to install.
RMS/BIG requirements for 8-packs structures: Ron gets to choose which is
easier – one loop for all MacNairs in tr09 and tr06, or one loop for each ioc
Will need to
be able to archive and set the gain (internal to module). (potentially
different for each module)
Will need to
have AES on structures in tunnel April 1stish
PLC checkout
(still true) Janice is
finished preparing the list. She hopes to start doing some of the checkout this
week.
Newplc
Has been installed.
2-pack PLC coming in
April-ish.
(still true) ~20 signals as
yet undefined. Janice will ask for TP
printouts for this PLC too…
NLCTA/8-pack summary display
(still true) Ron said he’ll
ask a SWE person to make it so DM displays can be CUDified (and Webified
thereafter). Once the DB is in place (2nd
priority after the proc loop), Janice will do final tweaks to the display and
we’ll be ready for CUDification.
Requests to not lose
-Target Power on trs8 (trs1 & 2 too?) proc loop
input panel (user enterable real, cmlog on change, save/restored)
-Missing energy for SLED and WGs
-------------------------------------------------------------------------------------------------
The Processing
Here's the plan for calculating
missing energy in the structures and sled system:
There are
enough cables/hardware to instrument two of the structure input forward
couplers. The plan is to instrument structures 6 & 8 (if they are
numbered 5-8 from up- to downstream). The missing energy for
structure 5 is struct 5 output forward - struct 6 input forward
struct 6 missE = struct 6 outfwd - struct 6 infwd
struct 7 missE = struct 7 outfwd - struct 8 in fwd
struct 8 missE = struct 8 outfwd - struct 8 in fwd
We will also ask software for a
SLED missing energy and two waveguide missing energies calculated as such:
SLED missE = sled M01 outfwd - sled
m01 infwd
WG6 missE = sled M01 outfwd -
struct 6 in fwd
WG8 missE = sled M01 outfwd -
struct 8 in fwd
that will not be used in the processing loop but will be
displayed on a panel and be archived.
All equations will have the form
A-B*C, where C is a user-enterable constant on a diagnostic panel.
