This listing is for 6 BRAND NEW Condition Outside ORIGINAL BOX: HOFSTRA PARTICLE ACCELERATOR TUBE TITANIUM NATIONAL ELECTROSTATIC TESLA ION COIL HVEE Electrostatic Particle Accelerator Van de Graaff Ion Implanter Tesla Coil as can be seen in the pictures.
TECHNICAL INFORMATION CAN ALSO BE FOUND BY CLICKING https://www.hofstragroup.com/product/dowlish-development-24-25-inch-electrostatic-particle-accelerator-injector-tube/
One of the tubes includes a Stainless Steel extention as can be seen in the pictures.
One of the tubes has the connector bent as can be seen in the pictures, nothing that affects operational integrity whatsoever and it is pretty simple to place it back together but we preferred not to do it so buyer can see it as is today.
These units came from The University of Michigan Dept of Nuclear Physics, they were bought for a specific research but ended up becoming surplus units and have NEVER been used at all, they are completely BRAND NEW outside the box so here's a chance to buy them at a fraction of the actual cost which was in the many thousands of Dollars $$$$$$$$$!

Advantages of Spiral Inclined Field Tubes
Unlike magnetic systems, electrostatic fields are equally effective in suppressing ions and electrons.
An electrostatic system avoids the additional ionization caused by the lengthened paths of low energy charged particles in magnet fields.
In contrast to the linear inclined field, the spiraling suppression field is of almost constant amplitude throughout the tube.
Since the field direction does not alternate, there are no regions at which the suppression field is zero.
Irrespective of where along the axis they are born, suppressed particles travel a nearly constant distance before interception, thus avoiding uneven loading and distortion of the voltage gradient.
Because the radial field is constant, good suppression is obtained with a small electrode inclination.
Three separate parameters may be varied in order to give minimum displacement of beams with widely varying mass, charge and injection energy. These parameters are the sense of rotation of the suppression vector, the number of pitches in each rotation and the rotation angle from pitch to pitch, which varies within a section.
The beam apertures in the electrodes are circular and the focussing fields therefore have cylindrical symmetry.
