PHYWE's largest diffusion cloud chamber: an 80 × 80 cm window onto natural radiation that classes, visitors and open-house crowds can gather around, all day long.
Continuously working large diffusion cloud chamber for visualization of natural ambient radiation.
| Mist fluid | Isopropyl alcohol, necessary accessory, not included |
| Consumption | 40 ccm / day |
| Refrigerant CFC free | R404A |
| Weight | approx. 480 kg |
| Power input | 230 VAC, 50 Hz, approx. 2.0 kVA |
All units adapted for 110V/60Hz. Contact us for volume pricing and grant assistance.
Alpha particles, electrons and cosmic-ray muons from natural background radiation leave trails of condensation in the alcohol vapor. Nothing is staged or simulated: this is what your students see.
The self-contained pedestal holds the cooling unit, power supply, alcohol tank, pump and timer. We help you plan delivery and placement.
Program daily operating times, weekends included, so the chamber is running whenever students or visitors arrive.
Background radiation and cosmic rays streak across an 80 × 80 cm surface, big enough for a whole group to watch together.
Each kind of radiation leaves its own signature. Within minutes, students start calling out what they see.
Alpha particlesShort, thick, bright and straight. Heavy and slow, they stop within a few centimeters.
Electrons (beta)Thin, faint and wandering. Light particles scatter easily off the vapor.
Cosmic-ray muonsLong, thin, straight lines that cross the whole chamber, arriving from the upper atmosphere.
This model runs on 230 V. Many U.S. buildings have 208/240 V circuits available, and our team confirms the right setup for your room before you order. If you need a standard 115 V outlet, the PJ45 115 V version plugs straight in.
No. The chamber shows natural background radiation and cosmic rays on its own.
Only isopropyl alcohol (2-propanol), which is fed automatically from the built-in tank. Typical use is about 40 ccm per day.
Yes. The built-in timer switches the chamber on and off on a schedule, including weekends, so it is ready when class starts.
About 128 × 128 × 128 cm and roughly 480 kg. We help you plan delivery, access routes and placement.
Tell us about your lab in the form above and we'll put together a complete, ready-to-teach configuration, so nothing is missing on day one.
Often, yes. Many institutions fund PHYWE equipment through NSF, Title IV and CTE programs, and our team can help you find and apply for the right opportunity.
