2026.09.19–20 2 days / 1 night Nishi-Waseda, Tokyo

An intensive retreat for students and mentors

Accel Kitchen Camp

Accel Kitchen Camp 2026

Take the experience you've built up observing at home and deepen it all at once over two days and one night. From taking detectors apart and rebuilding them, to hands-on measurement with radioactive sources, to a particle-measurement / PHITS hackathon — two focused days of getting your hands dirty alongside the peers you usually explore with from afar.

  • Free to attend
  • Travel stipend available
  • 2 days / 1 night
  • Bring your detector & PC
  • For students & mentors

Why

Why We're Holding This Camp

Because Accel Kitchen centres mainly on inquiry at home, the things that are hard to do there — assembling detectors, or measuring with radioactive sources — inevitably tend to be limited. Conversely, we came to believe that it is precisely because you already have measurement experience at home that you can take on deeper, more concentrated hands-on practice.

So we planned a two-day, one-night retreat: an intensive chance to understand how detectors work at a deeper level and to actually take measurements using radioactive sources. We hope it deepens your understanding of radiation measurement and becomes a springboard for pursuing your own inquiry more scientifically.

To widen the network among students living in different regions, we'll also create space to measure and simulate together, helping one another along the way. We'd be delighted if it became the spark for many collaborative research projects.
Schedule

How the Two Days Flow

DAY 1Day 1Build it, start measuring

  1. 13:00– 13:30 Introducing the new detector and new scintillators (GAGG, BGO and more)
  2. 13:30– 14:30 Assembling the detector (take apart, rebuild, swap scintillators)
  3. 14:30– 15:30 Microcontroller workshop (walk-through and flashing of the sketch files)
  4. 15:30– 16:30 Gain adjustment and background measurement of the detector
  5. 17:00– 19:00 Social gatheringsource measurements run in the background
  6. 20:00onward Check in at the hotel (Smile Hotel Kita-Asaka)overnight guests only

DAY 2Day 2Compete, then simulate

  1. by8:00 Check out of the hotel and head to the venueovernight guests only
  2. 9:00– 10:00 Gather and ice-breaker (jigsaw puzzle)
  3. 10:00– 12:00 Particle-measurement hackathon (split into groups and compete with a measurement of your choice)
  4. 12:00– 13:00 Lunch
  5. 13:00– 16:00 PHITS hackathon (by theme — J-PARC, KEK PF-AR, balloon flights, home cosmic-ray observation and more — plan your measurements in PHITS)
Program

What You Can Do at the Camp

The new detector in the flesh: a microcontroller and OLED display mounted on top of the scintillator box.

Upgrade to the new detector and take it home

Swap your own detector for the new model, fit the scintillator of your choice, and take it home with you.

  • Adjustable gain
  • Wireless connection over Bluetooth
  • More than 10× faster data acquisition than before
  • Built-in SD card as standard
  • Optional GPS
  • Connect up to four units at once
A detector calibration spectrum: ADC value on the horizontal axis, counts on the vertical axis, showing the X-ray, 212Pb, 228Ac and 208Tl peaks and the position of cosmic-ray muons.

Run experiments with radioactive sources

Take on measurements that are hard to do at home, using sources such as Cs-137, Co-60 and Am-241.

  • Calibrate your own detector against known peaks
  • Build an energy scale from real measurements — from X-rays, ²¹²Pb, ²²⁸Ac and ²⁰⁸Tl all the way up to cosmic-ray muons

Particle-measurement & PHITS hackathon

Measuring and simulating — drive your inquiry forward on both wheels at once.

  • Explore your own research theme with PHITS simulation
  • Find teammates to take on J-PARC, CERN and balloon experiments together
Notes

Before You Take Part

  • For those travelling from afar, we are arranging a travel stipend.
  • If you live in Tokyo, you may commute from home instead of staying overnight.
  • Depending on the number of applicants, we may carry out some selection.
  • Taking part requires a guardian's consent form.
