Service-Based Experiments

A significant proportion of user-initiated experiments at RARAF are service oriented. Service is generally characterized by a routine operation of our current technologies, in which we provide support, but not necessarily significant intellectual input. For such studies, users can choose to come to RARAF for their experiment, or samples can be sent to us for irradiation, and we will irradiate and return the samples. When needed, RARAF staff will provide appropriate training. RARAF guidelines defining a service-based experiment are:

1. The experiment is fully designed by the user with minimal input from RARAF staff;

2. The experiment uses existing facilities and requires at most minor modifications;

3. RARAF is acknowledged in all resulting publications but RARAF personnel are not necessarily co-authors;

4. A fee will normally be charged on a per-hour or per-day basis.

Broad-beam irradiations

Advanced imaging capabilities

Sample preparation

    • Fully-equipped, user-friendly biology laboratories adjacent to irradiation areas

    • Single-cell samples: mono-layers plated on a thin substrate or in flasks

    • Bulk samples: facilities for handling tissues, nematodes and fish embryos

       

Dosimetry – available for all irradiation modes

 

Application Process for Service-Based Beam Time

RARAF invite prospective service-based users to submit proposed experiments. We ask that prospective users discuss the proposed experiment with the RARAF Associate Director, Gerhard Randers-Pehrson, at (914)591-9244 or at gr6@columbia.edu. All applicants for service-based beam time should fill out a Service Experiment Request Form, which is available online: Service Request Form. Service-based applications are promptly evaluated, generally by the RARAF staff. When approved, beam time will be conveniently scheduled on a month-to-month basis.
