Phobos Spectrometer Detector Installation Procedure

 

I) Preparations in the RHIC tunnel: 1 person; at least 3 days before move

  1. Check weather report.
  2. Alert RHIC of upcoming restrictions at 10 o'clock.
  3. Arrange to have all obstructions removed from the tunnel and utility building.
  4. Arrange RHIC technician and truck.

II) Preparations in Chemistry building: 1 person; 1 day before the move

  1. Recheck weather report.
  2. Have the loading dock rearranged to provide clear access from the double doors to the roll-up door.
  3. Arrange for clear passage through the hallway.
  4. Arrange for security escort.

III) Preparation inside room 109 in Chemistry building

4 people, Gerrit VN, Heinz P, selected helper, and observer.

  1. Procedure starts with detector fully assembled and tested.
  2. Unbolt two survey posts from the floor; one on the side facing the double door and the next one in the clockwise direction (on the left facing away from the double door). and Move the posts out of the way.
  3. Unscrew the lucite cover and remove it.
  4. Remove all desiccant cartridges.
  5. Remove the bottom lucite cover.
  6. Remove module 1 from the small plate and store it in the transport box.
  7. Replace the bottom lucite cover.
  8. Check the brass latches which secure the pins at the three supports. Make sure that the pins are securely captured.
  9. Tie back cables as much as possible and secure the cooling tubes so they don’t drape below the cables.
  10. Unscrew the small plate transport frame from the stand.
  11. REMEMBER to take the screws to the tunnel.
  12. Replace the lucite cover and secure all screws. Tape edges of cover.
  1. Moving from room 109 to the van: 8 people
  1. Reconfirm security escort.
  2. Back up van to rollup door and open rollup and van doors (back door and both side doors).
  3. Have 4 equal stacks of bubble paper ready in van.
  4. Spread out the quilts on the van floor.
  5. Do final check for obstacles in corridor and loading dock. Open all doors.
  6. Four people pick up the transport plate using the handles on the corners.
  7. These four people carry the assembly out the door and through the loading dock to the van door. Two additional people go in front and two in back, prepared to replace one of the four in case of any problems.
  8. Once the group reaches the van, the two people in front go in the side van doors and kneel at the back edge of the van bed.
  9. The two front carriers hand off the assembly to the two people inside the van who start moving backwards.
  10. The two (former) front carriers stand at the side of the van door guiding the move until the back carries reach the door.
  11. Set the assembly down on the quilt.
  12. The back carriers place one had on the van floor and lift the handle with their other hand.
  13. Move the rest of the way into the van.
  14. The four people not carrying anything place the 4 stacks of bubble paper.
  15. The two back carriers and the two people kneeling in the van lower the assembly onto the bubble paper.
  16. Close van doors gently, making sure they are latched.
  17. Driving to RHIC: 4 people plus CAD technician with van
  18. Two people kneel in the back of the van, facing sideways, one in front and one behind the assembly.
  19. The van is driven in low gear at a speed not to exceed 7 mph, preceded and followed by security escort, driving around the ring in the counterclockwise direction.
  20. CAD technician unbolts support table from floor, transports it to the tunnel and sets it on the floor next to the double rack. It should be securely shimmed so that it doesn't rock.

V) Tunnel work while detector is driving

2 people plus CAD technician

  1. Check in parking lot, utility building, and tunnel for obstructions. Warn all people in the area of impending move.
  2. Disconnect closer on door inside security gate.
  3. Clear all personnel from the tunnel and close off access.
  4. Remove all of the fence sections on 11 o’clock inner side including the angled section. Remove all the fence sections on the 9 o’clock inner side except the angled section.
  5. Remove all floor post brackets to eliminate trip hazards.
  6. Verify that table is correctly located and secure.

V) Moving assembly into the tunnel

10 people

  1. One person stays in the tunnel at all time to restrict access to the area no longer protected by the fence.
  2. Clear all personnel and obstructions from the passage into the tunnel.
  3. Back the van up to the double door opposite the counting house.
  4. The procedure is the reverse of procedure IV with the people in front and behind also holding all doors.
  5. The assembly is placed on its support table sitting at the 9 o’clock side of the magnet. It is oriented with the extending cable ends facing away from the magnet.
  6. Remove the lucite cover, bolt the plate to the table, replace the cover and tape the edges.

 

VI) Moving assembly onto sliding plate - Preparation

  1. Personnel: Heinz, Carla, Patrick, Nigel, Kris, George, Gerrit, Peter, Wit & Bolek (passive observers)
  1. all other people should be cleared from the area
  1. Magnet power supply disabled by removing key
  2. no passage of anyone through the area during operation
  3. Close of orange mesh with stantions. (if necessary enforced by guard dogs)
  4. only 1 person will speak at a time, usually the person leading the action (Heinz, Gerrit) or the person which is performing a certain action (releasing handles, pin in place, etc)
  5. whenever one of the persons sees a problem, then this person should say STOP. the response of the other people will be that they freeze. action will only proceed after the person who issued the STOP has explained and the problem is resolved.
  6. Start position:
  7. small plate sitting on the transport plate on the table,
  8. lucite cover removed, desiccant removed, springs released,
  9. lifting jig in place. NOTE: Post and frame need to be labeled! Needs 3 people to install or remove it. All three screws must be turned simultaneously while lifting or lowering bars so screw threads don't catch in the bars.

  30. George, next to small plate, right of Gerrit, ready to catch the plate if it drops or to take over from Gerrit and to check that Gerrit doesn't hit any silicon
  31. Peter: Behind Heinz on the other side of the beam pipe.

 

VII) Move from table to the area of the spectrometer support:

  1. Gerrit gives instructions explaining lifting procedure, lift up on outer side of bars.

    c) When plate is rested, he holds support pin against post with on finger.

  12. Gerrit slides in the support pin closest to him in the slot (not too far otherwise the other pin will not go into its hole)
  13. Peter watches Heinz and Si edges from behind.
  14. Carla now will guide the support pin closest to her into its hole and secure it with its clip
  15. Heinz rests the plate on the temporary support, but holds it at all times
  16. Gerrit lets go of the lifting jig (after a couple of tugs to make sure that it is stable)

IX) Putting cantilever arm in place:

  1. Gerrit gives instructions
  2. Nigel, George and Gerrit lift arm, Kris has tools ready (English only)
  3. Nigel closest to the magnet, making sure the arm doesn't hit the silicon and guiding the support in place
  4. George supporting in the middle, making sure that the arm doesn't hit any silicon
  5. Move arm past cooling tubes for thermal shield (watch TOF!) and then guide it straight in.
  6. Gerrit fiddles with the bolts and gets the arm secured
  7. As arm is secured, Heinz lifts the plate to guide support pin onto support arm plate, Patrick watches from below.
