1. Light Sources for AMANDA/IceCube Cross-Calibration
Kurt Woschnagg
Integration Workshop
Berkeley, March, 2005

2. AMANDA in-situ light sources
Where are they?
How bright are they?
YAG not bright enough for interstring measurements. Closest string (17) useless.

3. Can AMANDA light sources be seen by String 21?
YAG laser
- all strings: fugghedaboudit
Nitrogen lasers
- LM I (str1): too dim
- LM II (str5): ~350 m
LEDs
- string 13: >400 m away
- string 18: ~400 m away
- string 14: ~400 m away
- string 19: ~350 m away
DC sources
can be seen m
- EUV (313nm, str9): maybe
- Rainbow (str7): not likely
flashers
shallow
string
Not looking good

4. Can AMANDA light sources be seen by String 21?

5. Can String 21 flashers be seen by AMANDA?
Closest strings see the light
but is is highly scattered
At 400 nm:
λeff ~ 20 m
λabs ~ 110 m
300 m
shallow
string
200 m
100 m

6. What about next year? Up to 12 new strings, closer to AMANDA
Plenty of IceCube strings within range of AMANDA light sources
Plenty of IceCube flashers within range of AMANDA strings
Standard Candle laser
Brighter than nitrogen lasers in AMANDA
Deploy in center of AMANDA or closest hole
Plenty of cross-calibrating light
