##     Amanda/IceCube Integration

- Amanda Integration 1.5.4

## Amanda Integration plan

- - Version from June 12, 2004  submitted to PO
- - Changes have been suggested in July
- - Then it became clear that this plan was much too
-   optimistic. Priorities at NH and Pole to other tasks.
- - New plan has to be written asap
- - The last weeks resulted in a much clearer picture about
-    what has been done and what is still to do.

- Amanda Integration 1.5.4

## Basic Idea 

- and string 21 (muons, IceCube flasher) as preparation
- for 2006 concident analysis
- 2006/07: First 10-25 IceCube strings + Amanda form a
- combined detector significantly more powerful than either
- alone.
- ( Season 2007/08: Raise MAPO )
- Finally: Amanda as high density nested sub-array
- with considerably lower  energy threshold than the
- full IceCube detector and capabilities much beyond
- Amanda‘s alone.

- Basic Idea

## „House raising plan“

- 05/06: raise ASTRO
- 06/07: disconnect from MAPO and raise VIPER
-            and DASI towers
- 07/08: raise MAPO  (max. one year later, i.e. 08/09)
-            by ~ 3 m
-  How many strings are long enough ?
-  Can too short strings be extended by patch cables ?
-  Move Amanda electronics to first flooor of MAPO ?
-  Get a final understanding of options in 2005
-     and in season 2005/06

## Time Synchronization between Amanda and IceCube

-  Send the IceCube GPS signal from ICH to MAPO
-    need 3 fibers
-   (H.Leich: GPS4TWR module in MAPO
- - Send strobe signal from Amanda DAQ to a DOM
-   main board in ICH (1 Hz).
-    1 fiber
-  Send Amanda trigger to a second DOM main board
-   in ICH (100 Hz)
-    1 fiber
- 5 fibres + 2 backups, prefer MM.
-            NO USE OF ELECTRICAL CABLES.

## Timeline

- Amanda Integration 1.5.4

## Amanda Trigger  GT 

- Only Amanda triggers to IceCube, no IceCube information
- to be used by the Amanda trigger.
- -  DMADD M18 trigger
- -  DMADD M12 trigger + TWR based volume trigger
- -  DMADD string trigger
- If a fast raw filter against downward muons can be
- implemented in the TWR system, the present M12
- can possibly lowered down to M7 or M6 without such
- a filter to M10 or M9.

## Reconstruction of merged events

- IceCube and Amanda  are both handled together
- in natural way by IceTray/dataclasses.
- System will be on track for handling a 30-32 string
- Detector in summer 2005.
- 2006: mergeand reconstruct events at NH and gain
- experience.
- Install online merging and reconstruction in season
- 06/07.
