#Introduction

The petiprobe is a combined probe, assembled on tokamak GOLEM in April 2019. It consists of the double tunnel probe and the combined ball-pen and Langmuir probe. Its name was directly translated from Czech, where it’s called “pětisonda” (“five-fold probe”), referring to its five measurements: Langmuir probe, ballpen probe, two tunnel probes and a Mach probe formed by the tunnel probe back plates. Measurements and reports to come soon.
