SVD DAQ and Overall DAQ for DESY Telescope

SVD DAQ and Overall DAQ for DESY Telescope Test Takeo Higuchi (KEK) I have a serious problem in the Internet connection. Automatic Windows update made my IE malfunctioning. The slides uploaded to Indico are not the latest one, sorry. Sep. 26 th, 2012 The 2 nd PXD/SVD Joint Meeting

Takeo Higuchi (KEK); PXD/SVD Joint Meeting DAQ’s Goal for the Telescope Test • PXD+SVD+DAQ+TRG are to have an integrated system test at DESY in Oct. 2013 to verify their whole readout scheme. • Goal of the test from DAQ’s view is to establish and verify the data-size-reduction scheme using HLT feedback to the PXD-readout system based on the ATCA (named Onsen system). Onsen: Japanese word meaning “hot spa” 2

12 Takeo Higuchi (KEK); PXD/SVD Joint Meeting Ro. I Finding • Position and size of PXD Ro. Is → Who will manage? – SVD-only tracking software to run in the HLT is surely needed, even which may be a simplified version from the actual Belle II tracking software.

Takeo Higuchi (KEK); PXD/SVD Joint Meeting Other DAQ Items • Global run control → Managed by M. Nakao-san. – PXD’s and SVD’s own run/slow controls are expected to be developed by each sub-group. • Online data quality monitor → Who will manage? – Checks on data corruption and event slip. – Data contents themselves are expected to be maintained by each sub-group. We will provide an example data-unpacker class for CDC. Please utilize it. How do we track (define the Ro. Is) in the beam test study? → Take SVD hit positions and interpolate them to PXD layers. 13

Takeo Higuchi (KEK); PXD/SVD Joint Meeting Challenge – POCKET DAQ • Mini Belle II DAQ (“POCKET DAQ”) for the telescope test – “POCKET DAQ” is a general purpose small DAQ system suitable for test experiments; “POCKET DAQ” is a shrunk version of the Belle 2 Link- and COPPER-based DAQ system. – We develop “POCKET DAQ” and utilize it in the telescope test. SVD R/O “POCKET DAQ” to be developed by DAQ Belle 2 Link 14

16 Takeo Higuchi (KEK); PXD/SVD Joint Meeting POCKET DAQ • Mini Belle II DAQ (“POCKET DAQ”) for the telescope test – We develop “POCKET DAQ” targeting the DESY telescope test and will utilize it there. SVD R/O “POCKET DAQ” to be developed by DAQ Belle 2 Link

17 Takeo Higuchi (KEK); PXD/SVD Joint Meeting Pre-Prototype of POCKET DAQ Snapshot in a neutron irradiation study to optical transceivers carried out in Kobe. Univ. from Sep. 6 th to 7 th, 2012. COPPER and TTD boot-up PC. Mini KEK-VME crate for COPPERs and TTD, TTIO, TTSW. In this case, MGTF cards (Bell 2 Link TX/RX) are mounted on the COPPER board. The present system requests your biggest “pocket”, though … Portable PS for the MGTF cards irradiated. Optical fibers binding irradiated and on-COPPER MGTF cards.

18 Takeo Higuchi (KEK); PXD/SVD Joint Meeting Timeline • Before the beam test: Discussion outputs from the SVD parallel sessions. – SVD FADC prototypes: in Mar. 2013 – FADC→FTB→COPPER readout test: in Jun. 2013 • DAQ group may be requested to make assistance for this. – System test including PXD: in Sep. 2013 • Originally, DAQ group expected that September was the time to setup DAQ paths roughly in ~three-week-works; fine tuning of the DAQ was considered to be made on the fly during the October beam test. • DAQ may need to work out our homework by one month earlier. – DESY beam test: in Oct. 2013 • No question at all. At when and to where, what items should DAQ group ship from KEK?

19 Takeo Higuchi (KEK); PXD/SVD Joint Meeting Summary • Goal of the test from DAQ’s view is to establish the datasize-reduction scheme using HLT feedback to the PXDreadout. • Responsible person’s name to the specific job (I think) are assigned. Items to do relevant to DAQ are (implicitly) listed in the slides.

21 Takeo Higuchi (KEK); PXD/SVD Joint Meeting Amendments AFTER My Talk [2] Written at 11: 00 am Sep. 26 th, 2012 by TH. • Magnetic field strength → 1. 2 T • Will the GT 3 surely be used in the telescope study? → consult Y. Iwasaki-san if he likes to join this program. • # of DHHs → 2 x DHHs + DHH-controller • # of ATCA(s) → 1 x ATCA • # of FTBs and HSLB cards → 2 x FTBs + 2 x HSLB cards

22 Takeo Higuchi (KEK); PXD/SVD Joint Meeting Amendments AFTER My Talk [3] Written at 11: 00 am Sep. 26 th, 2012 by TH. • Ro. I-finding software will be taken care by M. Heck-san using Jacob-san’s algorithm. • Assignment of a responsible person’s name for the online data quality monitoring (DQM) is a homework to the next meeting. • Event display should be prepared as a part of the DQM. • DAQ likes commodities (PCs) are purchased in Germany. → there exists possibility, but R. Itoh-san are requested to claim # of PCs and PCs’ specification.
