The Wilson Cloud Chamber Expansion Type, without sources, utilizes a vacuum pump to draw a partial vacuum, allowing for super saturation of the air with alcohol vapor. This classical design utilizes a pad soaked in alcohol to initiate the process.

The chamber utilizes an Alpha 'pin source' to ionize air particles along its path. As the ionized particles condense alcohol vapor, miniature foggy tracks are displayed inside the chamber, revealing the path of the Alpha particles. A light source, such as a microscope lamp, is necessary to illuminate the cell, and an Alpha material 'pin source' is also required. 

Kit Includes:

  • Base assembly with chamber sealed and clamped by 3x screws
  • Rod to support an Alpha point source through the side of the cell
  • Hand operated “one pull” vacuum pump with hose
  • Small squeeze bottle to hold a small amount radioactive powder, with chamois filter disc and complete with flexible tubing and Mohr clip
  • Base support rod, with knurled fixing screw permits the cloud chamber to be supported up from the table level for better viewing.
  • Holder for absorbers and for radioactive sources behind the absorber
  • Puffer bottle
  • Hose and spring clip
  • Vacuum pump
  • Support rod for lamp illumination

*Radio active sources and illumination lamp not included.

Wonderful
Super comfy and easy on and off, yet stylish imo! I could walk miles in these as a 56 yo and have worn them for three years! I hope they never stop making them. The only tweek I would suggest is to cover the footbed with leather or suede not cloth so they would last longer!

Lovely sandals!
I highly recommend! These are so comfortable! Right out of the box, they can be worn all day. The velcro-adjustable straps are great for making for a perfect fit. The aren't clunky to wear, even though they appear to be. They're super cute, in my opinion. The sock liner is textile, so feet feel good all day, not slimy, like leather and suede can sometimes make feet feel if socks aren't worn.

Cute and Comfortable
Size: 10, Color: Black
This is my second pair. I bought the sand color at my local Macy's. I got their last pair. I have issues with back pain and ankle swelling and pain. These are so comfortable I had to get them in Black. The adjustable straps are great. My feet are a little bit wider because of the swelling issues. So if you have very narrow feet these might be a little big. You might want to go down a half a size. But otherwise I wear a size 10 and they fit perfectly. I don't think the picture does the color justice. The black almost looks like velvet, it's very deep and rich. I wore them out today for the first time and got lots of compliments. The footbed is very comfortable with the memory foam. Lots of support. I noticed my back and ankle pain is much better wearing these. I've never owned UGG before. If these hold up really well and continue to stay comfortable, I will be purchasing other styles for fall and winter.
