Paper abstract: The study of protoplanetary disks has become increasingly important with theKepler satellite finding that exoplanets are ubiquitous around stars in ourgalaxy and the discovery of enormous diversity in planetary systemarchitectures and planet properties. High-resolution near-IR and ALMA imagesshow strong evidence for ongoing planet formation in young disks. The JWST MIRImid-INfrared Disk Survey (MINDS) aims to (1) investigate the chemical inventoryin the terrestrial planet-forming zone across stellar spectral type, (2) followthe gas evolution into the disk dispersal stage, and (3) study the structure ofprotoplanetary and debris disks in the thermal mid-IR. The MINDS survey willthus build a bridge between the chemical inventory of disks and the propertiesof exoplanets. The survey comprises 52 targets (Herbig Ae stars, T Tauri stars,very low-mass stars and young debris disks). We primarily obtain MIRI/MRSspectra with high S/N (~100-500) covering the complete wavelength range from4.9 to 27.9 {\mu}m. For a handful of selected targets we also obtain NIRSpecIFU high resolution spectroscopy (2.87-5.27 {\mu}m). We will search forsignposts of planet formation in thermal emission of micron-sized dust -information complementary to near-IR scattered light emission from small dustgrains and emission from large dust in the submillimeter wavelength domain. Wewill also study the spatial structure of disks in three key systems that haveshown signposts for planet formation, TW Hya and HD 169142 using the MIRIcoronagraph at 15.5 {\mu}m and 10.65 {\mu}m respectively and PDS70 using NIRCamimaging in the 1.87 {\mu}m narrow and the 4.8 {\mu}m medium band filter. ...
