Introduction

For many years Neutrino Physics and Particle Detectors have been a major part of Nevis Research Program. In July 2000 a new program has been established to move forward on research on development of a new particle detector for next-generation neutrino detectors at future colliding-beam facilities, the so-called Electron Bubble Particle Detector, utilizes the advantages of a cryogenic environment, and in particular on detectors using liquid Helium (or liquid Neon and Hydrogen) as the detecting medium.
More than thirty years ago it was learned that the stable state of an electron in liquid helium is a bubble of about 2 nanometer in diameter, with nothing but the electron inside. Electron bubbles ('e-Bubble') can also exist in liquid neon and liquid hydrogen. These e-Bubbles have physical properties that appear to be well-suited to detect the interactions of neutrinos, from natural sources such as the Sun and supernovae, and from accelerator beams and nuclear reactors, where the relevant energies are very low, where good spatial and energy resolution are required, and where a large detection volume is needed.
An active R&D effort on "e-Bubble" project is now underway. Since 2000, we hosted Nevis Summer Research Program for Undergraduates in summer each year. Education and training were a major emphasis of the program, with high school students, undergraduates and high school QuarkNet teachers working alongside Nevis scientists and technicians to determine the critical physics and technology issues, and to develop a conceptual design for a liquid helium solar neutrino detector. We will be hosting a similar workshop this summer. REU students joining the program would be based at Nevis Laboratories.
