Call 2024-VI
Electron Spin Resonance SR2024-II
Competitive access call 2024-VI for the Electron Spin Resonance laboratory is now open. The objective is to offer access to the facilities of the laboratory.
Opening: 11 October 2024
Deadline: 10 November 2024
The call SR2024-II will cover the ESR dose evaluation of Quaternary materials, including (i) Gamma irradiation*, (ii) UV bleaching and (iii) ESR measurements at low (<120 K) and room temperature by qualified users.
* For health and safety reasons, gamma irradiations will be carried out by CENIEH staff.
“Rate A” will be applied, as established in the general rules for accepted competitive access requests.
To submit your proposal, please register in the User Office before creating your request, or enter your user and password if you are already registered. Complete the Competitive Access tab and select the code SR2024-II.

Request for Electron Spin Resonance SR2024-II
Solicitud para Resonancia Paramagnética Electrónica: SR2024-II
Request for Electron Spin Resonance: SR2024-II
The objective of this call is to offer access to the facilities of the Electron Spin Resonance (ESR) Laboratory at CENIEH for activities related to the ESR dose evaluation Quaternary materials (mostly fossil tooth enamel and quartz), including (i) gamma irradiation, (ii) UV bleaching and (iii) ESR measurement at low and room temperature.
(i) and (ii) will be carried out by the CENIEH staff, while (iii) will be performed by “Qualified Users” only.
In order to be properly evaluated, the requests should include the following:
A brief scientific description of the project, including its relevance, originality and innovative nature.
A CV of the Principal Investigator. Note that the CV of other members of the research team may also be submitted for evaluation (although not mandatory).
Proposals should be submitted from 11 October 2024 to 10 November 2024. The call will remain open until 11:59 pm (Madrid time) on the last day. Any request received after the deadline indicated will not be evaluated for this call.
The following information should be also included in the proposal under the tab “General information in the Project / Experiment section” of the User Office portal:
The total number of samples to be processed, as well as the number of aliquots and irradiation doses per sample.
Whether the sample splitting in multiple aliquots prior to gamma irradiations will have to be performed by CENIEH staff (if so, this will imply an additional cost).
Whether ESR measurements will be performed at low (<120 K) or room temperature
The preferred time period for the ESR measurements.
Conditions
The analyses will be carried out between the reception of the samples and 31 December 2025.
A maximum of 300 samples (e.g., enamel) for room temperature ESR measurements and of 60 samples for low temperature ESR measurements will be accepted for this call.
The samples to be irradiated shall be preferably received before August 2025, after the publication of the results of the call. If not, the laboratory will be entitled to refuse the samples.
The samples will be preferentially processed following their order of arrival in the lab, although other factors (e.g., number of aliquots and irradiation times) will also be taken into account to optimize irradiation and measurement times.
Proposals including only the gamma irradiation of samples will not be considered for this call.
Facilities
Gamma irradiation will be performed on a Gammacell-1000 (Cs-137)
X-band ESR measurements will be performed at room or low temperature with either an Elexsys or an EMXmicro Bruker spectrometer.
