## FPD Summary July 11, 2000

-  Hard diffraction exists, but not well-understood:
-    large data samples and precise measurements needed
-  Large  c.m. energy  and luminosity of Tevatron necessary for
-   these measurements
**  ****FPD** will be a completely integrated sub-detector of  the DØ** **
-    detector:  Combination of quadrupole and dipole
-    spectrometers gives ability to tag both p’s and    ’s** **
**   **over large kinematic range, allows alignment,
-    understanding of backgrounds
-  Beams Division work for installation of FPD complete
-  Preparations underway for Engineering Run:
-   all Roman pot castles will be installed, some arms instrumented
-  Control of pots (motors) using DØ online system
-    has been tested
-  Detector production underway at UTA
-  Funding still not secured for phototubes and trigger electronics

## Quadrupole Castle

- Photo of a quadrupole castles installed in Tevatron tunnel.
- All 6 FPD castles were installed in fall of 2000.

## Engineering Run (9-10/00) 

-  **Setup a standalone DAQ system close to  D0CR.**
** ****Cabling (PMT, HV, TV, 1553, etc) SCR to Tunnel.**
** ****Installation of the castles in the beam line: Dipoles (fully equipped) + proton castles partially equipped**
** ****Installation of two full detectors and some scint.**
** ****Test of remote pot motion via a Python script.**
** ****Data taking.**
**Some problems found:**
** ****Everything takes longer than you think!**
** ****Rack monitor heating (noise from switch, fixed).**
** ****Flooding in the tunnel  (need umbrellas).**
** ****Loss of pot control (new procedures, safeguards).**

## Hit Reconstruction

-  This event (from Engineering Run data)
- represents a hit in our detector at the location:
- 	xd = 5.6 mm
- 	yd = 3.8 mm

## FPD Status 3/01/01

-  **All 6 castles with 18 Roman pots comprising the **
**  ****FPD have been installed in Tevatron**
-  Most cables and pot motion electronics installed
-   (~full time work for 6 FTE from Dec-Mar)
-  Electronic safety review  completed
-  Two complete detectors and four pseudodetectors
-   (trigger scintillator only) installed and waiting for
-    beam.
-   Testing of all systems underway
-   Work continues on trigger, software
-   Some additional funds ($38,000) secured by
-    Brazil, still need $67,000 to complete 10
-    detectors ($25,000 promised by DOE)

## May Shutdown Plans

-  Test upgraded pot motion program and
-    obtained pot motion approval
-  Continued cabling
-   Installed new cameras
-   Added a couple more pseudo-detectors
-   Many miscellaneous tasks
- At end of shutdown :
**Prepared  and approved  for collisions**
**Tunnel work should essentially completed**
**except for installation of additional**
**detectors**

## Pot Motion: LVDT vs. Encoder

##  Pot Motion Tests and Safeguards      

-  The pot motion software was upgraded and
-    extensively tested during the May shutdown.
-  The software is reliable and gives reproducible
-    results.  The pots always moves to the
-    desired position
-  The software verifies the direction of the
-    intended pot motion to make sure that it
-    is correct before the pot is moved.  If this
-    is not the case the command is reissued, and
-    if it is still wrong, the pot is returned home.
-  The drivers are disabled with a switch in
-    the SCR when the pots are not being moved.
-  The pots are hooked to an emergency line
-    which bypasses the software to send the
-    pots back to the home position.

##  More Pot Motion 

-  Smoke detector alarms disable the pot
-    motion (haven’t had any, but have tested).
-  An alarm is given if contact with the
-    IIB is interrupted.  If this situation continues
-    the emergency line could be used.
-  The pot positions are in ACNET as well
-    as variables which indicate all pots are
-    in home position, which are checked
-    by the MCR before beam injection.
-   Halo rates are displayed, and after some
-     experience is gained, alarms will be added
-     if the halo rate changes significantly.
-   A pot motion manual has been provided to
-    all shifters and a copy is in the SCR

## Pot Motion Tests

- Initially pot motion tests restricted to end of stores, so progresss slow
- Eventually gained confidence of BD, allowed to insert pots anytime

## Summer Run Plan

-  Dedicated FPD shifts with pots inserted
-    close to beam
-  Used stand-alone DAQ/trigger in
-   small control room
-  Full system tests (excluding DØ trigger)
-  Debugging, data-taking, algorithm
-   development, pot insertion procedure,
-   documentation, etc.
