    ================ * ================ * ===============

***************
1. Organization
***************
  DAQ working group consists of core (actual working)
persons + at least one person from other working groups.

     CORE   : M.Kohama(Kobe), A.Sakai, T.Kobayashi(INS), M.Shiozawa(ICRR)
     1kton  : Y.Fukuda, Y.Itow, M.Miura, Y.Suzuki (ICRR)
     VETO   : Y.Oyama(KEK)
     SCIFI  : M.Sakuda(KEK), Aoki(Kobe)
     LG     : T.Kobayashi(INS)
     Muon   : H.Ishii(INS)
     Beam   : T.Maruyama(Tohoku)
     Offline: T.Ishida(KEK)
     O.Sasaki, Chan kee, Wilkes, K.Nishikawa
     Adviser: Y.Yasu(KEK-Online)

 The existing mailing list 

                    "e362daq@pnahp.kek.jp"

is redefined to include the above persons.
Of course, you can freely request to be in the list
if you are interested in this subject.

***************
2. Frontend DAQ
***************
 Latest configuration of frontend DAQ system of each
detector component including a scheme of calibration were
reported.

 1kton: use TKO-ATM module + VME + Sun. Calib. can be done
        between the beam spills without any modification to
        the frontend electronics.
 VETO : 300ch in total. VME TMC(TDC mod.) + same ADC as LG-ADC.
 SCIFI: Flash ADC + VME FIFO.
        Sakuda(or ??) will check the possiblity of doing
        calibration using cosmic-ray muons between the beam
        spills.
 LG   : TKO-ADC or FASTBUS-ADC(not yet decided).
        Calibrate with Xe lamp between beam spills.
 Muon : frontend elec. board(atatched to chamber)
        + TKO memory module.
        Calibrate by using beam induced muons

***********
3. Sakai reported the framework of whole DAQ system.
***********
   DAQ system will be composed of network-connected VME
computers, a host workstation, and some monitor WSs.

    ================ * ================ * ===============
     The following sections were not disscussed deeply.
    ================ * ================ * ===============

4. Hardware list (except frontend)
			necessary	     present
FD
o VME crate             3 (1kton x 1 + FDx2)  1
o VME board computer    2 (Fine grainx2)      1(HP743rt)
o 1kton onl. WS         1 (Sun?)
o 1kton Sun-VME IF      1
o FASTBUS FPI		1		      1
o FASTBUS-VME IF	1		      1
o FD  onl. host WS	1 (HP/PC?)
o FD monitor WS		1 or 2(Sun/PC?)
o Storage(if local)	??

Beam channel
o CAMAC crate		5-10
o Onl. WS		6-15(PC)
o VME crate		1			1
o VME board comp.	1			1
o Host WS(cntrl,mon.)   1(HP/PC)

    ================ * ================ * ===============

5. To be decided (homework)
	o What should be online-monitored?
	o Data storage(local/CCPS)
	o Network configuration(FDDI/ether, private/public)
	o Data transfer protocol (NOVA?)
	o Type/OS of online computers(HP/PC/Sun)
	o Language for software
	o data format

    ================ * ================ * ===============

6. TODO
	o Aquire hardware
	o Hardware test
	o Development of online-DAQ software
	o DAQ test of each component
	o Test of whole system

============================================================
* Itow pointed out that we should consider slow control also.
