Abstract

a presente invenção refere-se a um sistema de resfriamento criogênico (10) que compreende um criostato (12), uma cabeça de resfriamento criogênico de dois estágios (24) e pelo menos um elemento de conexão térmica (136; 236; 336; 436) que é configurada para fornecer ao menos porção de uma trajetória de transferência de calor (138; 238; 338; 438) a partir do elemento do segundo estágio (30) ao elemento do primeiro estágio (26) da cabeça de resfriamento criogênico de dois estágios (24). a trajetória de transferência de calor (138; 238; 338; 438) é disposta fora da cabeça de resfriamento (24). uma resistência térmica da ao menos uma porção fornecida da trajetória de transferência de calor (138; 238; 338; 438) na segunda temperatura criogênica é maior que uma resistência térmica da ao menos uma porção fornecida da trajetória de transferência de calor (138; 238; 338; 438) na primeira temperatura criogênica.
