By measuring the beam current it could be determined whether the spot was originally a zero or a one, and a new value could be stored by the beam.
22.
"' 1999 "' World's highest proton beam current ISOL ( isotope online ) facility, lifetime measurements of 37-K at ISAC, TRIUMF becomes Canada's National Laboratory for Particle and Nuclear Physics
23.
Reducing the target voltage and increasing the beam current of the pick-up tube helped to mitigate the problem but, with early Plumbicons, this resulted in loss of resolution and increased lag.
24.
Secondly, since the klystron has beam current throughout the RF cycle, it can only operate as an inefficient class-A amplifier, while the grid of the IOT allows more versatile operating modes.
25.
The grid can be biased so the beam current can be cut off during part of the cycle, enabling it to operate in the more efficient class B or AB mode.
26.
Later, he also took responsibilities as the Coordinator of Systems Integration in the PS Beam Diagnostics Group; he also served as a Section Leader for Systems Integration and beam current transformers.
27.
A key difficulty is that the total supplied beam current needs to be multiplied by the number of parallel beams ( e . g ., 10 million ), which dramatically increases cost of ownership.
28.
Where T is the time to expose the object ( can be divided into exposure time / step size ), I is the beam current, D is the dose and A is the area exposed.
29.
An array of small Faraday cups or a Faraday cup on mounted on a linear manipulator can be used to measure the distribution of the beam current across the spot; this shows the beam uniformity.
30.
(1 ) Beam power The power of the beam [ W ] is the product of the accelerating voltage [ kV ] and beam current [ mA ], parameters easily measurable and precisely controllable.
