Basic Operations for KLS Operators

Following operations can ONLY be conducted by KLS operators listed below. If someone wants to be added into this list, please contact Bing Shan. Current eligible laser operators are,

Bing Shan                                            Ali Alnaser

Jiangfan Xia                                        Stefan Voss

Mahendra Shakya                                Mikhail Zamkov

Shambhu Ghimire                                Pengqian Wang

Please come to Bing Shan if you have any question about the operations. At least one operator should be responsible to the whole system whenever the laser is on. This person is usually designated in the weekly laser schedule.

ECR/LINAC Beam Alignment

 

  1. Close Valve a to block the Ti:sapphire laser; Open Valve b;
  2. Use Mirror1 and Mirror2 to make the He-Ne beam go through the two iris;
  3. Use two silver mirrors to direct the beam to the far end of the lab;
  4. Open Valve a, use mirror 3 and 4 to align Ti:sapphire to He-Ne (overlapped both near and far-field;
  5. Close Valve a, remove two temporary silver mirrors;
  6. Tune the mirrors in vacuum beamline to make the He-Ne beam on target;
  7. Open Valve a. Ti:sapphire beam should be on your target.

 

Evolution-30 LBO Temperature Control

 

  1. Hold both ­ and ¯ keys for more than 5 seconds until see the ALM menu;
  2. Use Ä key to see ALo;
  3. Set lower limit to working temperature-1;
  4. Use Ä key to see AHi;
  5. Set higher limit to working temperature+1;
  6. Press ¥ to finish setting.

 

Other possible settings: PId1 (PID), InP1 (Input 1), InP2 (Input 2), Out1 (Output 1), Out2 (Output 2), gLbL (Global)
