Commissioning Workshop ESS – JPARC: Instrument Session

Tuesday 11 Oct 2022, 10:30 → 18:00 Europe/Stockholm

Titanium

This is a parallel Session of the Main Meeting:  https://indico.esss.lu.se/event/3079/ 

Registration should be done on the main meeting page.

• All contributions should prepare a presentation (share and upload before the meeting) and leave time for discussions (e.g. 15+10). 

• Confirmed physical attendees from J-PARC for this session: Ryoichi Kajimoto, Kosuke Hiroi, Maiko Kofu, Toshiya Otomo, Daichi Ueta

 

Participation by zoom will be possible (ATTENTION: The main meeting has separate zoom links that you find on the indico page!):

Meeting ID: 555 070 3148

 

Non-exclusive selection of guiding questions for the workshop (@Instrument speakers: Please include relevant topics in your individual presentations where you see fit):

• What teams are involved in the commissioning – is that different per instrument / per component? What are their roles?
• What software are used for instrument control? Who is responsible for the controls? (Is there any EPICS at J-PARC?)
• Any special tools (hardware/software) that are used for commissioning/calibration solely?
• Have you documented the commissioning procedures (and how)?
• How often are instruments setups re-checked (re-commissioned, re-calibrated, etc)? What triggers this? How much of this work is automated?
• What were the main lessons learned that you did not expect before?
• Examples of commissioning a particular type of measurement (that does not concern the whole instrument) and overlap with other instruments. 
• In the early days, could the data be correlated / linked to a given pulse?
• How is neutron instrument data acquisition and storage done? (E.g. through a common data storage approach or individual handling for each instrument.)
• Fast/high data volume/beam synchronous acquisition, what has happened at J-PARC in the last 3 years?
• How do you communicate with other parts of the facility? (e.g. Accelerator + Target commissioning preparations)
• What was the process of building and commissioning the instrument suite at J-PARC concerning controls? How did it evolve at your instrument?
• If there is a safety deviation during commissioning / operation, what are the actions to follow when reporting?

1 Introduction to Instrument Parallel Session

• What do we want to get by the end of the Workshop?

Speakers: Andrew Jackson (European Spallation Source ERIC), Asami Sano, Daria Noferini (European Spallation Source ERIC), Maiko Kofu, Robin Woracek (European Spallation Source ERIC)

2 Overview J-Parc instruments

• Timeline, when was each instrument commissioned
• Peculiarities to the instruments

Speaker: Toshiya Otomo

3 Overview ESS instruments

• Instrument Suite (incl. Beamline Scientists), Peculiarities to the instruments
• Overview of choppers, detectors, SE, polarization, ...

Speaker: Andrew Jackson (on-site)

4 The neutron source characterization at BL 10 NOBORU (Test beamline)

• If possible include experience with beam profile (spectrum and spatial variations) on whole instrument suite.
• Keep in mind relevant questions raised by the control and safety teams (outlined below) and include in your talk where possible.

Speaker: Masahide Harada (online)

5 Example ESS Commissioning Plan (System Validation Plan): LOKI (SANS)

• Details of LOKI
• More technical detail on HC than general overview on day 1

Speaker: Judith Houston

12:00 Lunch

6 Example JPARC Commissioning: Spectrometer (BL01)

• Focus on beam characterization (flux, spectrum, spatial distribution, pulse shape, detectors/BM’s, detectors, etc.):
• How to get from first neutrons to first experiments
• Keep in mind relevant questions raised by the control and safety teams (outlined below) and include in your talk where possible.

Speaker: Ryoichi Kajimoto (on-site)

7 Example ESS Commissioning Plan (System Validation Plan): ODIN (Imaging)

• Details of ODIN
• More technical detail on HC than general overview on day 1

Speaker: Manuel Morgano

8 Example JPARC Commissioning: Imaging (BL22)

• Focus on beam characterization (flux, spectrum, spatial distribution, pulse shape, detectors/BM’s, detectors, etc.):
• How to get from first neutrons to first experiments.
• Keep in mind relevant questions raised by the control and safety teams (outlined below) and include in your talk where possible.

Speaker: Takenao Shinohara (online)

14:10 Break

9 Discussion: Safety

• collect safety related questions form the individual instrument contributions
• Collect few relevant examples (can each presenter think of at least one example?)
• ESS Safety (Thomas Hansson) will be present to address open questions.

10 Discussion

• General discussion
• Discuss needed equipment for commissioning and beam characterization
• Prepare feedback for main close-out session

11 Controls of Neutron Instruments

10min presentation: Overview J-PARC controls of instruments (Yasuhiro Inamura )
10min presentation: Overview ESS controls of instruments (ECDC, ICS)

• Collect all controls aspect from previous contributions and discuss open questions n this time slot.
• Control group responsibles from JPARC (no central control group) and ESS (ICS, DMSC/ECDC) will join for this time slot specifically

Speaker: Yasuhiro Inamura
