kilovoltist
A kilovoltist is not a recognized term in physics or electrical engineering. The standard unit for electric potential, or voltage, is the volt. Prefixes are used to denote multiples or submultiples of the volt. For example, a kilovolt (kV) represents 1,000 volts. Therefore, a "kilovoltist" would not refer to a specific person, device, or phenomenon.
In discussions related to high voltages, the term "kilovolts" is commonly used to describe electrical potentials
It is possible that "kilovoltist" might be a colloquial or invented term used in a specific, non-standard
