Improving inverse Compton sources by avoiding non-linearities / B. Terzić, G. A Krafft, V. Petrillo, I. Drebot, M. Ruijter. - In: EUROPHYSICS LETTERS. - ISSN 0295-5075. - 129:6(2020), pp. 62001.1-62001.7. [10.1209/0295-5075/129/62001]
Abstract:
We present a new, more nuanced understanding of non-linear effects in inverse Compton sources. Deleterious non-linear effects can arise even at low laser intensities, a regime previously viewed as linear. After laying out a survey of non-linear phenomena which degrade the effectiveness of inverse Compton sources, we discuss two powerful techniques designed to avoid these non-linearities. Starting with the known technique of non-linear longitudinal chirping of the laser pulse in the high laser field regime, we show that the simple stretching of the laser pulse, while keeping the energy constant, can significantly increase the spectral density of the scattered radiation in many operating regimes. Our numerical simulations show that combining these two techniques avoids detrimental non-linearities and improves the performance of inverse Compton sources over an order of magnitude.
