Daniel Thomas Liquid Supply and Circulation December 4, 2006 Motivation To create an inexpensive, selfmaintained, liquid supply system to be incorporated into the Large Perpetual Cloud Chamber (LPCC) Design Requirements Minimal maintenance Safe Quiet Inexpensive Long lasting Design Features Cost Currently our team has spent ~$150 This does not include a sufficient reservoir or heat bath which is estimated ~$175 Currently our team also needs to purchase a better pump which will be estimated ~$200 Total cost of approximately $525 Test of Design Cloud Chamber Workshops went very well Allowed for the design to be perfected 3 times Ideas: no heat bath, positive displacement pump, danger of timed circulation Conclusion The overall design of the liquid circulation system seems to be very prominent and well thought out The construction of the design is definitely on the right track
