skottsekunder

Skottsekunder, literally “shot seconds” in Swedish, is a domain-specific term used to describe the time interval between successive events in a sequence of shots or detections. It is not a formal SI unit and there is no universal international definition. The exact meaning of skottsekunder varies by field and practice, so authors typically specify what constitutes a “shot” and how the interval is measured when they use the term.

In ballistics or firearms testing, skottsekunder may denote the time separation between consecutive shots in a test sequence. In experimental physics, detector instrumentation, and related areas, the term can refer to the inter-arrival time between detected events such as photon arrivals, ionizations, or electronic triggers. Because of this context dependence, the term is largely informal and its interpretation is tied to the specific experimental setup or measurement protocol.

Measurement of skottsekunder is usually carried out with devices such as chronographs, high-speed sensors, or time-to-digital converters that record timing with the required resolution. The observed values can range from milliseconds to seconds or longer, depending on the application, firing rate, and event rate being studied.

Notes and caveats: Skottsekunder should not be treated as a standardized unit. When used, it is important to clearly define the scope, including what counts as a shot, how the interval is timed, and the exact units or resolution reported.
