Bilateral comparison of the H*(10) calibration coefficients for photon radiation

Project Description

This comparison will compare calibration coefficients in terms of H*(10) for photon radiation.
A transfer chamber will be used. Six radiation qualities are selected: N-40, N-80, N-100, N-200,N-300 and  S-Cs.

A transfer chamber will be provided by PTB and the comparison will be funded as agreed by involved parties: PTB and IMBiH.

The project has been completed and the report can be downloaded here>>.

Progress Report 2023-10-02

IMBIH finished measurements in January 2022.
Finally, PTB performed stability check measurements in March 2022.

Measurements in progress, afterwards Draft A and B will be completed

Progress Report 2022-01-20

The intercomparison started in September 2021, due to changes in protocol and approval of final protocol by TC-IR which was finalised on 23 September 2021.

PTB performed the first set of measurements in October 2021, IMBIH just finished measurements and will send the chamber back to PTB by the end of this week. Measurements at IMBIH took longer due to holiday season and COVID-19 situation where laboratory had to be closed.

There is one more set of measurements to be done at PTB afterwards (February 2022), and hopefully the project will end at that time.
