| * Change the 1K lens in the corridor: remove the smooth one, place the corrugated one. See a small default that hadn't been seen before on a section of the lens: groove ~5mm wide, ~0.1-0.3mm deep, ~5-7cm long. Probably acceptable; decide to keep the lens, Samuel will simulate the effect with Zemax. | * Change the 1K lens in the corridor: remove the smooth one, place the corrugated one.

Back to the NIKA2 run 5 main page
September 2016, 17 (Saturday)
- Finish mounting NIKA2 back in place.
- Start leak tests.
September 2016, 16 (Friday)
- Arrival at the telescope of Samuel.
- Unload truck dismount NIKA2 nose, roll NIKA2 body it in the corridor.
- Dismount NIKA2 body, up to the cold stage optics.
- Change the 1K lens in the corridor: remove the smooth one, place the corrugated one. See a small default that hadn't been seen before on a section of the new corrugated lens: groove ~5mm wide, ~0.1-0.3mm deep, ~5-7cm long. Probably acceptable; decide to keep the lens, Samuel will simulate the effect with Zemax.
- Change the 100mK lenses in the servo room (floor below the receiver cabin). Here also a small known default on 2 of the 5 lenses: ridge ~0.5mm wide, ~0.3mm high, along 2 perpendicular diameters. Before coming Samuel estimated with a simplified simulation it was acceptable, he will simulate more accurately the default.
- Change the 2mm array: replace the 1100 KIDs array with the new 660 KIDs array.
- Change the dichroic.
- Start mounting again everything together.
September 2016, 15 (Thursday)
- Arrival at the telescope of Johannes, then Alessandro, Martino and Aurelien with the truck.
