Introduction

For this document, it is assumed that a minimum of two people are present at the firing:

  • The Firing Director (FD)
  • The Safety Officer (SO)

However, it is suggested that the following people be present as well:

  • The Operations Overseer (OO)
  • The Data Recorder (DR)

For more on the positions, see Responsibilities of the Rail Gun Team.

  1. Place voltmeter on the EMRG and turn it on. If the voltage is above 5V, stop working on EMRG!
    • Place voltmeter on the EMRG and turn it on.

    • If the voltage is above 5V, stop working on EMRG!

    • Use the discharge stick on the grounding plates to drop voltage below 5V.

  2. Check to see that there are no obstructions down the rails. If so, remove obstructions.
    • Check to see that there are no obstructions down the rails.

    • If so, remove obstructions.

    • Ensure bleed resistors are functioning properly and are connected to the rails.

    • Engage braking mechanisms on wheels and place holding chocks behind wheels.

  3. Remove jet fuel and other flammable materials from area around the EMRG

  5. Bolt target lead onto frame at the appropriate length from the muzzle of the EMRG Bolt target lead onto frame at the appropriate length from the muzzle of the EMRG
    • Bolt target lead onto frame at the appropriate length from the muzzle of the EMRG

  6. Torque on all bolts along the rail to be 30 foot-pounds. Start from the air-injector end work from top to bottom, back to front in a zig zag pattern.
    • Torque on all bolts along the rail to be 30 foot-pounds.

    • Start from the air-injector end

    • work from top to bottom, back to front in a zig zag pattern.

  7. Ensure grease is on all connections. Connect main power cables to rails Connect main power cables to rails

  10. Place full nitrogen injector tank into cradle and latch down with chain.
    • Place full nitrogen injector tank into cradle and latch down with chain.

  11. Set the HSC Shield Box (HSCSB) in view of barrel profile. The camera must be AT LEAST 1.5 meters from the rails. Plug browser and Ethernet cables through the hole in the back of the HSC and hook them up to your electronics.
    • Set the HSC Shield Box (HSCSB) in view of barrel profile.

    • The camera must be AT LEAST 1.5 meters from the rails.

    • Plug browser and Ethernet cables through the hole in the back of the HSC and hook them up to your electronics.

    • Open the top of the HSCSB to avoid overheating the camera.

    • Turn the lights on, then turn them off after you have checked accessibility.

  12. Remove shorting blocks from the resistor bank.
    • Remove shorting blocks from the resistor bank.

  13. Raise manual discharge plate and place manual discharge pin. Raise manual discharge plate and place manual discharge pin.

  14. Open Phantom Camera Control Plug extension cord powering lights and high speed camera into wall.
    • Open Phantom Camera Control

    • Plug extension cord powering lights and high speed camera into wall.

    • When the camera is accessible by the computer, open the camera pool window and check that the camera is accessible

  15. Place experiments Place break screen and attach leads Check electrical continuity!!
    • Place experiments

    • Place break screen and attach leads

    • Check electrical continuity!!

    • Test the measurements and make sure the connections to the physical data acquisition system are correct and functional.
