Timing matters. At PITZ, the laser-struck photocathode generates electron bunches that are accelerated immediately, at up to 60 million volts per meter. A fast electromagnetic kicker system acts as a high-speed gatekeeper, selectively deflecting individual electron bunches from a high-repetition beam and steering them according to researchers’ needs. This precise, bunch-by-bunch control is essential for fine-tuning beam properties for FLASH experiments and other radiation therapy studies.

Anthropic's Tool Search goes further: tools marked defer_loading: true stay out of context until Claude searches for them, cutting ~85% of upfront token cost. But it's Claude-API-only, and when a tool is fetched, the full JSON schema still enters context (~121 tokens/tool).
