Christian Pauly, Wuppertal, CBM, DiRICH
The DiRICH-DAQ is for the readout of 1000 MAPMTs for CBM RICH. 
One DiRich module has 32 channels. A back-plane holds several DiRICH 
cards a combiner module and Voltage supply board (LV + HV). 
There are no cables anymore beside of networking.
The amplifier x30 uses 10mW power. The Combiner board has a 2.4GB/s link,
in moment. For 1 mV Signals one achieves 61 ps timing resolution.
Data format is  4byte leading + 4 byte trailing + 4 byte overhead.
Laser pulses were measured with scope and compared with DiRICH.
The measured MAPMT timing precision is in the order of 300ps.
MCP XP85012 shows about 220 ps. 15k channels is 104kEuro

Markus Pfaffinger, Erlangen Lifetime measurements of an PHOTONIS XP85012
This sensor has no ALD coating. The gain goes up to 3e6 at 2kV.
QE is 26-30% (29 at 380nm). The timing resolution is about 39ps (1e6 gain)
typical for 25um. The rate stability is 30% drop at 1e6 gain and 1e6 rate/cm2.
The ALD sensors of PHOTONIS 2" and Hamamatsu 1"show low aging.
The 2" of Hamamatsu show some aging at 1 C/cm2 (60%). A second one looks better,
no damage seen.

Merlin Boehm, Erlangen, Quality assurance test Box
Light tight copper-box for measurement of gain, time resolution, cross-talk,
and QE. A timing resolution of 200ps was achieved, needs to be improved,
there is electronic noise. There is also a positioning system
for laser measurements. He showed the scan of a 6x128 pixel Hamamatsu tube.
Cross talk and laser halo was observed.

Mustafa Schmidt, Giessen, Updates of the DISC Software.
Mustafa showed how the software package deduced the logarithmic likelihood.
He assumes 1 nm roughness, 21ps timing, position 1.5mm, and a
momentum resolution of 10MeV/c. He gets 3.8 s.d. pi/K separation.
For 365-460nm he gets 4.1 s.d. at 16 degree. Opening the bandwidth
filter worsens the separation power due to dispersion. The f0(1500)
was reconstructed with and without disc DIRC within Pandaroot and
the reconstruction efficiency was doubled. He also showed some results
from the beam time 2016.

Roman Dzhygadlo, GSI, CERN 2016 prototype test
Roman showed the prototype used in 2016 with the 9-MCP-detector plane.
The beam particles were tagged by TOF. The electronic time resolution was 13ps.
It is a distribution from 9 up to 25ps. Timing resolution for particles were
170 with and 200 ps without walk correction. The plate simulation for
pions agrees well with the data. Proton and pions show a clearer difference
in timing spectra with the cylindrical focusing in data. Separation is
2.8 w/o and 3.1 s.d. with lens (7 GeV/c, 25 deg.)

Klaus Foehl, Giessen, Test-beam with the latest prototype 2016
Also Klaus introduces first the prototype, a fused silica plate with
read out modules attached. The test was done at Desy/T24. The readout performed
by the DAQ with TOFPET asics. They achieved a photon resolution of 6 mrad.
The timing between pixels was about 460 ps.

Erik Etzelmueller, Giessen, Status TDR Endcap Disc DIRC
Eric shows what has changed in the TDR. Prototype tests were added,
extended MC-simulations and update of MCP-PMT results from Erlangen.
Additional options like other MCP-PMTs, different band pass filter,
numbers of ROMs, and air-gap vs. cookies were added.
In May a updated version of TDR to the Cherenkov group will be presented.

Jochen Schwiening, Test beams 2017 at CERN
Jochen briefly explains the situation of the test beams at CERN. The time
slot August/September is foreseen. The option to shift the beam time
to October/November is out of scope. Everybody is invited to join.
The goal is to use a new cylindrical lens and to use 3x5 MCP-PMTs.
Also measurement with a tilted plate are foreseen. It serves also to add the
plate to the TDR as a addendum.
