How Low Can You Go? (Part 2)

Synopsis: Looks at the technology required to achieve high vacuums. Shows a large chamber at NASA/JPL which is regularly evacuated for the testing of satellites and their components before they are launched into space. Illustrates a benchtop laboratory system using a rotary and diffusion pump set. The physics of a Parani is explained in terms of transport properties in the Knudsen regime. Shows details of the test programme for the new space telescope, and how a vacuum system or an industrial scale can mimic the conditions deep in space.*

Notes: NB. As of May 2016 Open University Worldwide are no longer distributing DVDs. They have posted this message on their website: ‘Unfortunately Open University Worldwide Limited has decided that product sales are no longer viable given the reduced funding to Higher Education institutions and diminishing demand for the products we have traditionally stocked. At present the Open University Students Association (OUSA) will continue to sell the "Good Study Guide", and we are in discussion with other possible distributors to continue to make The Open University’s products available for purchase. As soon as we have any information on other channels of distribution we will update this notice’. Some products are still available via second hand dealers on Amazon.co.uk
