Conlusions of the Cracow Meeting

April 24, 2020

Wolfgang Lohmann, DESY

IFJ PAN Cracow

TPC

BeamCal and LumiCal (Example LDC, 14 mrad):

LumiCal

HCAL

BeamCal

• precise (LumiCal) and fast (BeamCal) luminosity measurement hermeticity (electron detection at low polar angles) mask for the inner detectors GamCal ~150 m downstream for fast luminosity April 24, 2020 IFJ PAN Cracow

New results in LumiCal simulation studies:

Bogdan, Iftach, Ivan, Pavel, Alexandra.

Some results not in agreement, results relevant for FE Asic design should be documented.

Eudet note ? Mokka implementation now almost completed BeamCal/Pair Monitor Simulations Andrey, Eliza, Uriel, Yosuke First part needs to be finalised and published/written down FE Electronics design and Test Jan, Krzysztof, Elena, Angel, first results to be prepared for publication 5/7/2008 April 24, 2020 IFJ PAN Cracow

New results on sensor studies BeamCal:

Konstantin, Sasha, Sergey, several results ready for publication Sensors for BeamCal Andrey, Eliza, needs to be finalised and published/written down Sensors for LumiCal Wojtek, mask design in progress, first prototypes in autumn 2008 Laser alignment system Krzystof, tests in a small size prototype To be extended to larger scale prototype/interferometry Mechanics Woitek, progress for LumiCal, also integration into ILD April 24, 2020 IFJ PAN Cracow

Additional interesting talks:

CLIC detector (Lucie) First LHC results (Piotr) Super Belle group proposal (Yosuke) Possible LumiCal Sensor planes for Super Belle (Leszek) April 24, 2020 IFJ PAN Cracow

Coming Meetings and Conferences:

• June Warsaw: Calorimetry - LumiCal performance studies (Iftach, Bogdan, Ivan) - FE ASIC design and tests (Marek, Jan, Krzysztof ..) - Sensor tests (Konstantin, Sasha, Martin..) MDI - beamdiagnostics with BeamCal/GamCal (Andrey) IEEE (Octobre, Abstract NOW) FE ASIC design (Marek) single crystal diamond beam tests (Sergey, Martin) EUDET Meeting (Oct. 6-8, Amsterdam) FCAL meeting in Belgrade (Octobre) LCWS Chicago April 24, 2020 IFJ PAN Cracow

Where we are:

• Design studies of the calorimeters relatively advanced Open issues - realistic detector, including calibration uncertainties, cross talk, noise…..

- realistic beam transport simulations - beam-pipe shape - design studies for GamCal Hardware activities must be enhanced April 24, 2020 IFJ PAN Cracow

• • We found new partners in US, Japan CERN has interest, extending FCAL to CLIC However: • About 80 Physicists signed the report to the PRC - here we are 30 - in the table of ‘FTEs’ working for FCAL I count 25 - engineering support is far from sufficient - diploma students will finish- need replacement - funding in Europe is tight, in US it is far from adequate - support for testbeam activities is not sufficient.

Remember: EDR should be ready in 2012 April 24, 2020 IFJ PAN Cracow

Testbeam and Hardware Milestones

We had a first nice experience with the EUDET testbeam Infrastructure at DESY More testbeam this/next year??

ASIC tests will be continued in the lab. Next steps Irradiation test at DALINAC – just discussions about 1 week testbeam in the fall of the year Laser alignment prototype ready in 2009 (Cracow) FE ASICS prototypes ready in 2009 (Cracow and Fully equipped sensor plane ready in 2009 DESY, TA) April 24, 2020 IFJ PAN Cracow
