- Distinguish the goals of the 3 years where we could do test beams:
	
		- 2021: R&D.
 
		- 2022: R&D - common DAQ integration.
 
		- 2023: Common DAQ integration - detector validation - combined test beam.
		  
	
	 
	- It would be nice if all the detector test beams are announced in advance to allow parasitic participation by another subsystem.
	  
	- Up to now in DESY the test-beam facility had 3 independent lines with electrons of energy (1 - 6  GeV) but with particle multiplicity of 10^3 - 10^4 ( https://particle-physics.desy.de/test_beams_at_desy/ ).
	
		- A new line (R-Weg using dumped beam) is being developed that will allow high particle multiplicity ( 10^8 - 10^10) in energy range (0.5 - 6.5) GeV.
		
			- Not completely clear when it will be available (early 2022?), and what the beam parameter will be, in particular what can be changed, and what will be the beam size.
			
				- Will ask test beam coordinators.
				  
			
			 
		
		 
	
	 
	- Halina added test beam facilities at the end of the agenda.
	  
	- For simplicity let’s call 10^3 - 10^4 single particles test beam and 10^7 - 10^9 high rate test beams.
	  
	- Since one need to ask now if one want some test beam time in 2021, here are the wishes for the people that participated:
	  
	- Calorimeter: want to test new GaAs and Calice Si sensors.
	
		- Want to do a single particles test beam campaign in fall 2021.
		  
	
	 
	- Cherenkov: want to perform
	
		- In Fall 2021 joining single test beam campaign will be enough, high rate test in 2022 in DESY if available.
		  
	
	 
	- Scintillating screen: Buying equipment (camera+screen) now.
	
		- In Fall 2021 could join single particles test beam campaign for now to exercise DAQ.
 
		- High rate tests have already been done at CERN with similar technology and particles multiplicity so no rush to retest it for now.
		  
	
	 
	- Backscattering calorimeter:
	
		- Want to irradiate Lead glace blocks. Will look where and how to do it.
 
		- In parallel need to start putting together a lab soon to allow working on experimental setup.
		  
	
	 
	- Tracker:
	
		- May want to join single particles test beams if feel confident with module received now, but no strong commitments for now.
