## Calorimeter Test Beam

- Goals
- Test of hardware technologies
- Feasibilities, properties and performances of various detector technologies; aging, linearity, responses, resolutions, etc
- Feasibilities of digital hadron calorimetry
- Data for simulation validation and improvements
- Data for shower libraries for realistic simulation of jets
- Magnetic field effect
- Single particle track-cluster match
- Dates: Starting early 2005 (CALICE ECAL) – early 2006
- Proposed rough detector sizes
- 30 cm x 30cm x 20cm for ECAL (~20X0)
- 1m  x 1m x 1m HCAL – 1.3mx1.3mx1m (5~6 0)

## How do we organize?

- When do we want to do this and for how long?
- Late 2005 early 2006?  Why? For a few years...
- Where do we do this?
- Based on the necessary particle types, momentum range, availability, Fermilab seems to be the best place to do this.
- Who are the participants?

- What is the setup for testbeam?
- Who builds which part of the setup?
- Each sensitive gap technology construct their own sensitive gap detectors?
- What about DAQ?
- Front-end?  Backend?  Data recording?
- How about absorber plates for sampling calorimeters?

## What is the readout granularity we want?
How do we organize TB software development?
In what time table do we work?
Where do we obtain financial support for coordinated effort?  DOE?  NSF?  Each group figure out by themselves?
What are the other detector groups’ efforts? 
We need to work together with them to approach facilities as a concerted group effort.
