DAQ Update for DUNE Small TPC CE Test at Fermilab

Today’s Topic

8/9/18 Wanwei Wu | DAQ Update for DUNE Small TPC CE Test at Fermilab2

• ORC Preparation• DAQ Status and Next• Electronics Layout/Timing/Trigger

• SLAC team locates the COB etc.a. COB from JJ (James J. John, Russell), has 3 DPMs.b. SLAC will make sure the firmware is up to date when sending

it to Fermilab.c. Discussions are ongoing regarding previous safety review

findings on the COBd. DPM and RCEs will come along with COBe. Patrick has RTM at CERN and will send to Fermilab.f. An FPGA Carrier Board is needed for the timing system. One

may be available at CERN.

• SLAC team can send the COB etc. in the following weeks.• We are working on one ORC review for the whole DAQ system.

DAQ Status and Next—ATCA Shelf

8/9/18 Wanwei Wu | DAQ Update for DUNE Small TPC CE Test at Fermilab6

• Need to connect to one of the servers

• Request remote login for setup, for Matt (mgraham), JJ (jrussell) and Sergio (username?)

• Matt has access to PAB server now

DAQ Status and Next—COB and RCE

8/9/18 Wanwei Wu | DAQ Update for DUNE Small TPC CE Test at Fermilab7

• Optical fiber connects (from) the WIB to RCEs. There is an IP on WIB and specific UDP ports on FEMB.

• IP addresses: SLAC assign them using DHCP but fix them in the dhcpd.conf. (Also, MAC addresses provided by JJ)

• A static IP address for the shelf manager that also needs to set up on the 1GbE network (may already works since we are using the same PCs).

• Get an IP to the shelf manager setup• Have access to the software• Use various commands to integrate the RCEs and COB• This is documented on a SLAC confluence page (but need a SLAC

computer account to access it)• Need to modify IP if taling to shelf manager

DAQ Status and Next—Software

8/9/18 Wanwei Wu | DAQ Update for DUNE Small TPC CE Test at Fermilab8

• A meeting has been scheduled with CD on coming Monday. We will

present our software request:a. What hardware is involved.b. What expertise we have and can bring to the table.c. What expertise and support we need from CD.d. Are there any quicker solution than full-blow artdaq

acceptable• Kurt and John are busy with protoDUNE. We’re contacting them to

find some time to setup the DAQ software.

TPC Electronics—Trigger

8/9/18 Wanwei Wu | DAQ Update for DUNE Small TPC CE Test at Fermilab11

• How will the trigger signal be

generated?

• David Newbold provided an

option: replicate the CERN setup

which uses the AIDA TLU - this unit is

specifically designed to make

coincidence triggers from scintillators,

and can connect directly to the timing

system�David Cussans, who is the

designer of the TLU�.

From David Newbold

To use four scintillators two on top and two on bottom to make a cosmic trigger, …

• a dump of the power draw. (This is with the RCE doing basically nothing,

so the draw will depend somewhat on load. 35Watts is the what the

shelf manager has allocated to each DPM (2 RCEs). The DTM has a

smaller FPGA so is less. )
