WORKSHOPS · outreach work Now booking for 2026

To your school, to your museum —
detector in hand,
we'll be there. In half a day, participants build a particle detector, measure cosmic rays and radiation, then discuss the data with researchers and present their findings — that is our outreach workshop.

01 how a day unfolds

In 3–4 hours, build, measure, analyze.

Here is how a typical "cosmic-ray detector workshop" unfolds over a day.
For STEAM sessions, booth formats and school visits, we rearrange this structure to fit.

Participants working together as a team to assemble a detector 1
BUILD · 50 min
Assembling the detector
To understand how it works, teams take a detector apart to see what is inside, then work together to build one of their own.
A participant measuring cosmic rays with the detector they assembled 2
MEASURE · 40 min
Taking measurements
Using the detector they built, participants measure cosmic rays and radiation. They vary the conditions to test their own questions — changing the zenith angle, shielding with books, or moving to another floor to study how the ceiling's thickness affects the count.
A participant graphing measurement data and building an interpretation 3
THINK · 30 min
Compiling and interpreting the data
Participants graph their measurement data and build their own interpretation, comparing it against the predictions and hypotheses they made beforehand.
Participants discussing their interpretation with junior- and senior-high staff 4
DISCUSS · 30 min
Going deeper through discussion
Participants discuss the interpretation they reached with Accel Kitchen's junior- and senior-high staff, taking it further.
Each group presents its inquiry and measurements and receives feedback from researchers 5
SHARE · 30 min
Presenting and feedback
Each group presents the inquiry and measurements it carried out, and researchers give feedback in response.
02 voices from the room

Participants'voices.

This workshop turned my view of research — and of science itself — around by 180°. I had always pictured research as stiff and old-fashioned, but it turned out to be so free, something I could start even now, something thrilling. I came away genuinely interested, and the time felt truly worthwhile.
Building a radiation detector and measuring cosmic rays/ Osaka University SEEDS Program
Starting from "what even is a cosmic ray?", the explanations carried me all the way to being genuinely interested in research. Thanks to that one step of "actually running the experiment yourself," everyone's presentations made immediate sense. I used to think of science as a dull subject you just memorize at school, and honestly I didn't like it — but I came to see again that it is a field close to everyday life, one where inquiring into even a single thing can open up enormously: a field overflowing with possibility.
Hands-on cosmic-ray measurement/ Komatsu High School
I had been interested in space for a long time, so I joined this inquiry. I knew nothing about cosmic rays, but through the experiments and building the cosmic-ray detector my understanding deepened a great deal. I discovered the joy of generating new questions of my own from experiments and their results, and I was really glad I took part.

04 frequently asked

Questions we often get before a booking.

Q.01 Is there a fee? +
It depends on who is commissioning the workshop (a school / public body / company / local government), the scale, and whether joint funding is involved.
It helps if you let us know your expected scale and budget when you first get in touch.
Q.02 Will you bring the equipment? +
Yes — Accel Kitchen brings the detectors and parts. All you generally need to provide on-site is power, desks and chairs. With an internet connection, we can also arrange to bring in overseas researchers online.
Q.03 How many people can you accommodate? +
For the hands-on format (build + measure), the standard is groups of 4–5, up to 40 people total.
For a whole grade or a hall-sized audience, switching to a booth or demo format lets us handle more than 100 people.
Q.04 Can you run it outside Tokyo — in the regions, or on remote islands? +
Absolutely. We have run workshops in Nagano, Miyagi, Aichi, Osaka, Chiba, Kanagawa, Saitama and beyond.
For locations that require travel and lodging, we just ask to discuss those costs in advance.
Q.05 What do we need to have ready on the day (power, internet, room)? +
The bare minimum: one ordinary classroom / desks and chairs for every participant / a few power outlets / Wi-Fi or wired internet that reaches the desks.
If you want to include an outdoor measurement segment, having a route to a rooftop or grounds makes it richer.
We confirm the details in a pre-event meeting, so there is no need for you to prepare any special equipment.
Q.06 Can we consult you from the planning stage? +
Yes — we welcome inquiries right from the planning stage. "We'd like to do something for junior- and senior-high students, but haven't settled on a theme," or "only the budget and number of days are fixed" — please reach out even at that stage.
Drawing on past cases, we can suggest a few formats likely to suit your school or museum.
