Describe KAGRA/Subgroups/VIS/OpsManual/FishingRods here.

This page describes the status of the fishing rods.

Beam splitter

  • At 25 ºC it's possible to use the fishing rod to set the keystone at nominal position (8125).

  • at 24.5 ºC or lower it's not (8645, 11465).

  • Range: from -2500 µm to +4900 µm in the LVDT and from -1,400,000 to +1,400,000 steps in the stepper motor (7694). What was the temperature that day?

Standard Filter

  • It's been at its lowest position since the temperature was 25 ºC. We set the keystone to 488 µm and couldn't move it down more (8125, 8645).

  • Range: from -700 µm to +700 µm in the LVDT and from -870,000 to +835,000 steps in the stepper motor (3558). What was the temperature that day?

Bottom filter

  • This fishing rod didn't seem to have any problems before but we haven't tried to use it at every temperature condition we've had.
  • Range: from -1000 µm to +1800 µm in the LVDT and from -746,000 to +746,000 steps in the stepper motor (3280).What was the temperature that day?

SR2

Top filter

Range: [ -1,700,000 , 1,500,000 ]

Stardard filter

Range: from -750 µm to 1000 µm in the LVDT and from 300,000 to 1,000,00 steps in the stepper motor (4431).

Bottom filter

Range: from -500 µm to 600 µm in the LVDT and from -550,000 to -250,000 (4430).
