Popis: Intense laser‐interaction experiments examining fast‐electron production and energy deposition in solid‐density plasmas were performed. Strong K‐photon emission suppression with decreasing target‐foil volume was observed. This observation is consistent with L→K and M→K electron transitions being affected by target heating. Bulk‐electron temperatures of at least 200‐ to 300‐eV are inferred for the smallest mass targets. Target heating is attributed to fast‐electron recirculation inside the target.
